# The first person to fly faster than the speed of light was?

No human has flown faster than the speed of light, as it is currently considered impossible based on our understanding of physics. The speed of light, approximately 299,792 kilometers per second, is the cosmic speed limit according to the theory of relativity.

# Who was the first American to win thew Nobel Prize for measuring the speed of light?

The first American to win the Nobel Prize for measuring the speed of light was Albert A. Michelson in 1907. His precise measurements helped advance the understanding of the fundamental constant and its significance in physics.

# What is the scientific notation of speed of light?

The scientific notation for the speed of light is 3.0 x 108 m/s, or, 3 x 105 km/s depending on the units you're using (meters or kilometers).

# What is the refractive index for araldite CY 230 and HY 951?

The refractive index of Araldite CY 230 and HY 951 is typically around 1.54.

# Could the human eye see the speed of light in space?

No, the human eye cannot see the speed of light in space. The speed of light is extremely fast, traveling at approximately 186,000 miles per second. Our eyes are not designed to perceive such high speeds directly. However, we can indirectly observe the effects of light and its propagation in space through various scientific instruments and technologies.

# How much faster does the speed of light travel than a plane?

The speed of light is approximately 186,282 miles per second, whereas the average speed of a commercial jet is around 500 miles per hour. This means that the speed of light is over 670 million times faster than a plane.

# Can you tell your eye refraction level from your contact prescription?

Yes, your contact prescription includes information about your eye refraction level. It indicates the amount of correction needed for your vision, measured in diopters, to bring your eyesight into focus. This information helps the optometrist or ophthalmologist determine the type and power of contact lenses you require.

# What does the Refractive index of a material signify?

The refractive index of a material signifies how much light slows down when it enters that material compared to its speed in a vacuum. It is a measure of how much the material can bend or refract light rays. Different materials have different refractive indices, which can impact how light interacts with them, such as causing light to be bent when passing through a lens.

# How can you convert the speed of light in km per second by dimensional analysis?

To convert the speed of light from meters per second to kilometers per second using dimensional analysis, we can set up a conversion factor. One kilometer is equal to 1000 meters, so the conversion factor is 1 km = 1000 m. Therefore, we can multiply the speed of light in meters per second by the conversion factor to get the speed of light in kilometers per second.

# How much time you need for 15km with the speed of light?

Since the speed of light is approximately 299,792 kilometers per second, it would take only around 0.00005 seconds to travel a distance of 15 kilometers at that speed.

# What is the clearest image produced by a lens?

The clearest image produced by a lens is obtained when the lens is properly focused and there is no aberration, distortion, or other optical imperfections. This results in a sharp and clear image with accurate representation of details and minimal blurriness. The clarity of the image is influenced by factors such as the quality of the lens, the aperture setting, and the distance between the lens and the object being photographed.

# What happens when light traveling at an angel passes from one material into another?

When light traveling at an angle passes from one material into another, it undergoes refraction. Refraction is the bending of light as it passes from one medium to another, due to the change in the speed of light. The degree to which the light bends depends on the angle of incidence and the refractive indices of the materials involved.

# Does the speed of light have anything to do with image resolution-clarity of modern TV?

No, the speed of light does not directly affect the image resolution or clarity of modern TVs. Image resolution and clarity depend on factors like the display technology, pixel density, and image processing capabilities of the TV. The speed of light refers to how fast light travels, which is crucial in transmitting the images to your TV, but it does not affect the resolution or clarity of the displayed image.

# Would a ball dropped from the same height fall faster on hit the ground first on the moon or on earth?

It appears that you wish to know which would result in falling faster, parachuting from an airplane flying above the earth, or parachuting from one flying above the moon.

The moon has no air, so whether you use a parachute or not would make no difference. You would fall at an acceleration of about one-sixth that of earth, or about 1.6 meters per second per second. The velocity at which you hit the ground depends on the height. It's the square root of twice the height times the acceleration. From 10 meters up you would land at 5.6 m/s, which might be survivable. Perhaps you could try to land on top of your useless parachute, as a cushion. From 100 meters you would hit at about 18 m/s, which is over 40 miles per hour. From "regular" airplane height, 1000 meters or more, your impact velocity would be over 60 m/s.

In earth's atmosphere your fall would be limited to perhaps 200 km per hour even without a parachute, because of the friction of the air on your body. With a parachute, you could fall very slowly, perhaps 10 km/h (that's like 3 m/s or 6 miles/hour) or less, and avoid injury.

The greatest difficulty in your experiment would be flying the airplane above the moon, because (as we already noted) the moon lacks an atmosphere. Instead you would need to use a rocket, or build a tall tower from which to jump. In either case, you would almost certainly be killed upon striking the ground, regardless of the moon's lesser gravity. As an exercise, you should calculate the greatest height from which your fall would not cause you injury.

Some of the numbers shown here are undoubtedly in error. Velocities are shown in miles/hour, m/s and km/h, and the conversions between them were sloppy. See

http://en.wikipedia.org/wiki/Equations_of_Motion

for the correct equations, and work out the actual consequences of your experiment for yourself.

# Is the brain faster than light?

Speed of light is a lot faster than the electro-biochemical events that our brain runs on.

# Are quarks traveling at the speed of light?

Quarks have not been observed to exist separately - they are "confined" within larger particles such as protons and neutrons, that are made up of several quarks (3 each, in the case of protons and neutrons).

# What is the only time that light waves travel at the speed of light?

Light always travels at the speed of light.

The only time that's 299,792,458 meters per second ( " c " )

is when it's traveling in vacuum.

# What is the fastest speed of anything in universe?

The fasted "known" speed in the universe is the expansion of the universe itself, at about 74km/s per 3m lightyears. That is incredibly fast. The fastest obseved would be light at of course, lightspeed, or rougly 300,000,000m/s.

# The speed at which a wave travels through a medium is called?

The Speed At Which Wave Travels Is Known As Wave Velocity.It Is Denoted As 'v' which Equals The Product Of Its Frequency And Wavelength.

# How fast can light travel in a second?

Sunlight takes about 8 minutes, nineteen seconds to reach Earth so that is about 499 seconds.

# Why cant the speed of light be exceeded?

In our Universe, any attempt to exceed the speed of light, as viewed in any frame, by a particle with mass, will be defeated by the laws of the Universe we happen to live in. Whether or not we like that fact is irrelevent: that's the laws of this Universe.

It arises from the fact that an object getting close to the speed of light will get more and more massive as it gets closer and closer. Because of that, it will become harder and harder to make it go faster, as it takes more energy to accelerate an object with more mass.

# Five examples of acceleration?

-- Start a car moving from a stop-sign.

-- Slow a car down when approaching a stop-sign.

-- Turn a corner in a car.

-- Turn a corner on a bicycle.

-- Turn a corner on roller-skates.

-- Throw a stone at a stop-sign.

-- Drop a stone into a pond.

-- Throw a stone horizontally half-way across a pond.

-- Throw a stone up to get it all the way across a pond.

-- The moon sailing around the Earth in its orbit.

-- Practically every motion of anything that you ever see during daily life on Earth.

We're in the category of here, so we need to be a bit careful about

how we handle scientific terms like this.

Contrary to popular usage, "acceleration" does notmean increasing speed, and

an object that's accelerating is not necessarily expected to be moving faster.

Acceleration means any change in speed ordirection of motion, and any object

that's not moving at a constant speed in a straight line is accelerating.

A car speeding up after leaving a stop-sign is accelerating, with positive acceleration

because its speed is growing. A car slowing down as it approaches an intersection

is accelerating, with negative acceleration because its speed is shrinking.

A car or bicycle on a curve, as well as the moon and any other object in a gravitational

orbit, is accelerating, because, although its speed may be constant, the direction

of its motion is changing.

And while we're being more precise than usual, velocityand speed are two

different things. Everybody knows what speed is. Velocity is speed and the

direction of the speed. If you drive around a curve at a steady 30 mph (48 kmph),

is changing.

And any change of velocity is called . . . . . acceleration.
