Yes! Radiation or radiant energy is energy that comes from a source and travels through space at the speed of light.

Does a computer screen use the RGB or the CMY colour model?
Does a ray of light undergo total internal reflection if it strikes the boundary between water and air above a critical angle?
Yes! The critical angle for light approaching the boundary between water and air is the angle of incidence above which it undergoes total internal reflection.
Does a wave with a low frequency have a long wavelength?
Yes! A wave with a lower frequency has a longer wavelength and a wave with a higher frequency has a shorter wavelength.
Does an electromagnetic field have a component electric and magnetic field?
Yes! An electromagnetic field has a component electric and magnetic field and propagates through space in the form of bundles of energy called photons which are configured as electromagnetic waves, the force carriers of radiant energy.
Does chromatic dispersion take place as white light travels from air into a raindrop?
Yes! Every wavelength of light is affected to a different degree by the refractive index of a transparent medium and as a result, changes direction by a different amount when passing from air to water or water to air.
Does chromatic dispersion take place as white light travels from air into glass?
Yes! Every wavelength of light is affected to a different degree by the refractive index of a transparent medium and as a result, changes direction by a different amount when passing from air to glass or glass to air.
Does each wavelength of visible light correspond with a unique spectral colour?
Yes! Every spectral colour corresponds with a single wavelength of visible light.
Does energy increase with frequency?
Does light bend towards the normal as it crosses the boundary between air and a raindrop?
Does light bend towards the normal as it crosses the boundary between air and glass or water?
Does light travel faster in air than in glass or water?
Yes! Light travels faster in air than in either glass or water.
Does light travel faster in air than in raindrops?
Yes! Light travels faster in air than in water.
Does light undergo chromatic dispersion as it enters a raindrop?
Yes! Chromatic dispersion takes place as light crosses the boundary between one transparent medium and another if it has a different refractive index.
Does light undergo refraction as it enters glass?
Yes! Refraction occurs as light crosses the boundary between transparent media with different refractive indices.
Does light undergo refraction as it travels across the boundary between one transparent medium into another?
Yes! When light leaves a vacuum or travels from one transparent medium into another, it undergoes refraction causing it to change both direction and speed.
Does the amplitude of an electromagnetic wave correspond directly with energy it carries?
Yes! The greater the amplitude of an electromagnetic wave, the more energy it carries.
Does the brightness of the bands of colour in a primary rainbow drop off sharply on the outside of each arc?
Yes! If each of the bands of colour that forms a primary rainbow is thought of as a disc then the brightness of each colour drops off sharply at its circumference.
Does the colour of a ray of light change as it travels through different transparent media?
No! The colour of a ray of light remains the same as it travels through different transparent media because whilst its speed and wavelength change its frequency is not affected.
Does the optic nerve transmit visual information towards the brain?
Yes! The optic nerve is composed of the axons of ganglion cells and transmits visual information assembled within the retina towards the geniculate nucleus and the visual cortex.
