Visible Light Spectrum

Raindrops in the atmosphere act as prisms, dispersing sunlight and creating rainbows when the light is refracted and reflected within them. This phenomenon results in the separation of different wavelengths of light, creating the familiar rainbow colors in the sky.

Yes named as photon. It has momentum though it does not have mass

Its momentum is given by the expression p = h / l

Here h = Planck's constant and l - lambda the wavelength of radiation

Yes, electromagnetic waves encompass a wide range of wavelengths, with visible light falling within a specific portion of that range. Shorter wavelengths, such as ultraviolet and X-rays, have higher energy and frequencies than visible light.

Visible light can't move a compass needle because light consists of electromagnetic waves, while a compass needle is affected by the Earth's magnetic field. The magnetic field from visible light is not strong enough to influence the orientation of a compass needle.

Monochromatic light is light of one wavelength. E.g. A red laser has one single wavelength and is therefore categorised as 'monochromatic light'. A standard light bulb emits light of many different wavelengths across the visible spectrum and therefore is not 'monochromatic light'.

Pulsars emit pulses of radio waves because their strong magnetic fields accelerate charged particles, causing them to emit these waves. The energy distribution of the particles in a pulsar's magnetosphere favors radio waves over visible light.

Ultraviolet radiation is of higher energy than visible light. Ultra-violet suggests that it is above violet in the spectrum, and the colour violet is the uppermost region of visible light.

An object appears a certain color because it reflects specific wavelengths in the visible spectrum while absorbing others. For example, a blue object reflects blue wavelengths and absorbs other colors.

One common place to see all colors in the visible light spectrum is in a rainbow, which is formed when sunlight disperses and refracts through water droplets in the atmosphere. In addition, certain minerals and gemstones can exhibit a wide range of colors due to their composition and structure.

Visible light has wavelengths ranging from approximately 400 to 700 nanometers. Different colors within the visible spectrum correspond to different wavelengths, with violet having the shortest wavelength and red having the longest.

Beta wavelengths are not stronger than visible light. In fact, beta waves are a type of electromagnetic radiation with higher frequency and energy than visible light, but they are generally weaker in terms of their ability to penetrate materials and cause biological damage compared to visible light.

Light, in fact, all electromagnetic waves, travels at approximately 186,282 miles per second.

( In a vacuum. Slightly slower when passing through something like water or the atmosphere or a solid body such as yourself )

Brightness is just your perception of luminous intensity, measured in candelas, and is in general much more closely related to the amplitude of the wave rather than the speed of it.

Chlorophyll and carotenoids are substances that can absorb visible light in plants. Additionally, dyes and pigments used in various applications can also absorb visible light, leading to their characteristic color appearance. Metamaterials and semiconductor materials are examples of inorganic substances that can be engineered to absorb visible light for specific purposes.

The visible spectrum from low wavelength to high is as follows: Red (750-620 nm), Orange (620-590 nm), Yellow(590-570 nm), Green (570-495 nm), Blue (495-450 nm), Violet (450-380 nm)

in compton scattering it is necessary that the energy of the photon should be very much greater than binding energy of electron .. binding energy is equal to work function of metal . in most of metals , the threshold frequency is equal to that of ultravoilet light .that is why we do not observe comption effect with visible light.

VIBGYOR- Violet, Indigo, Blue, Green, Yellow, Orange, Red

(bottom to top order in spectrum)

Red pigment absorbs wavelengths of green and blue light, while yellow pigment works by absorbing blue light. Therefore, the colors not absorbed by red pigment are green and blue, and the color not absorbed by yellow pigment is blue.

While I wasn't able to find a specific name associated with the unification of the electromagnetic spectrum, I would suspect that it was James Clerk Maxwell, the man who discovered the link between electricity and magnetism, thus coining the term "electro-magnetic".

The spectrum itself is just a list of the ranges of energy that a photon can be at. By studying visible light we can develop the equations that eventually lead to everything from radio waves to gamma waves.

No, electromagnetic radiation includes a wide range of wavelengths beyond visible light, such as radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays. Each type of electromagnetic radiation has different properties and uses.

Light rays can transmit through an opaque object when the object is thin enough for some light to pass through. This can happen if the object is not completely solid or if it has tiny openings that allow light to pass through. In these cases, some of the light will be able to transmit through the object despite it being considered opaque.

Violet (purple) is the highest energy color in the visible spectrum. It has a wavelength of about 400nm (4x10-8m), the lowest of all visible light.

A prism separates light into the visible spectrum, which includes the colors of the rainbow. It does not separate light into the entire electromagnetic spectrum, which ranges from gamma rays to radio waves.

White light contains all the colors of the visible spectrum. When white light passes through a prism or water droplets creating a rainbow, it separates into the different colors of the visible spectrum: red, orange, yellow, green, blue, indigo, and violet.

A fluorescent light bulb contains a phosphor coating on the inner surface of the bulb, which converts ultraviolet light produced by the mercury vapor inside the bulb into visible light. LED light bulbs do not contain phosphors but instead use semiconductors to directly convert electrical energy into visible light.

Cones in the retina are the receptor cells that enable us to distinguish different wavelengths of light. There are three types of cones that are sensitive to different wavelengths, allowing us to perceive colors.
