If energy has mass and anything that has mass cannot travel at the speed of light then how is light energy?
Light is composed of massless particles called photons, which allows it to travel at the speed of light in a vacuum. While light carries energy, it does not have mass in the traditional sense, which is why it can achieve this incredible speed.
What is the average number of days that the South Pole has no sun light each year?
The sun rises once each year at the South Pole, and sets once each year. The average number of days in a year without a sunrise at the South Pole is 182.5.
How can the technique of this experiment be used to determine whether any two different colors of light such as red light and blue light travel at the same speed inside the plastic?
To determine if red and blue light travel at the same speed in plastic, one could shine both colors of light through the plastic at the same angle and measure the time it takes for each color to travel a set distance. If the times are equal, the speeds are the same. However, if there are differences in the times taken, it suggests that red and blue light have different speeds within the plastic.
You have three 3-way switches operating 3 ceiling lights you want each switch to operate each single light What do you do?
To have each switch operate a single light, a 3-way switch must be installed for each light. Each switch needs to be wired to its respective light, with one wire running between the switch and light fixture. This way, each switch will control the light it's connected to independently of the others.
How does light travel to the cerebral cortex?
Light enters the eye and is focused by the lens onto the retina at the back of the eye. The retina contains light-sensitive cells called photoreceptors that convert light into electrical signals. These signals then travel through the optic nerve to the visual cortex in the brain, which is located in the cerebral cortex, where they are processed and interpreted as vision.
How many days can a test match last?
A cricket test match spans 5 days. This entails two batting and two bowling innings' per side. Depending on weather the test match can be shortend to any number of days but each team still has the same number of innings'.
What are three mediums light can travel through?
Light can travel through air, water, and glass. Each of these mediums allows light to pass through due to their transparent properties.
How many hours and minutes of sun light are there on each of these days?
The answer is given after the list of "these" days.
How do you see light spectrum?
The human eye perceives the visible light spectrum, which spans from violet to red. When light enters the eye, it is interpreted by specialized cells called cones, each sensitive to different wavelengths of light. The brain then processes this information to create the perception of color.
How many days would it take to get from Jerusalem to mecca by caravan?
A caravan can travel between 25 to 30 miles each day. It will take 30 days for a caravan to travel from Jerusalem to the Mecca.
What does light energy travel in?
Light energy travels in the form of electromagnetic waves. These waves consist of electric and magnetic fields that oscillate perpendicular to each other and to the direction of travel.
How long did it take to travel to the moon?
If you are a beam of light , it would take you 1.4 seconds. The Apollo spacecraft of the 1960s and early 1970s took 3 days (72 hours) each way.
How many days are in between each period?
Around 5-6 days. Depends if your flow is light or heavy
The zone of fire in front of each hunter spans about?
get rid of obama
What are 3 materials mediums light can travel through?
Air, water, and glass are three common materials that light can travel through. Each material has different properties that affect how light travels through it, such as its density and refractive index.
A scientist traveled 80 km each day how many km did he travel in 10 days?
800km
What is the distance in km to travel 600 light years?
Each light-year has approximately 9.5 x 1012 kilometers. You can multiply the number of light-years by that number.
