Which of the following occurs as light travels from its source?

Which of the following occurs as light travels from its source?

Which of the following occurs as light travels farther from its source? Far from the source, photons come together in a small area. The intensity of light increases as photons move away from the source.

Which of the following occurs as a light wave bends when it passes?

From these definitions, refraction occurs as a light wave bends when it passes from one medium into another.

Which type of wave needs a source of energy to produce it?

A mechanical wave requires an initial energy input. Once this initial energy is added, the wave travels through the medium until all its energy is transferred. In contrast, electromagnetic waves require no medium, but can still travel through one.

When droplets of water in the atmosphere act like prisms the color in the sunlight undergo?

Rainbows: Refraction of the Seven Colors of the Spectrum A rainbow has seven colors because water droplets in the atmosphere break sunlight into seven colors. A prism similarly divides light into seven colors. When light leaves one medium and enters another, the light changes its propagation direction and bends.

Which of the following is necessary for light to travel?

But unlike sound waves or water waves, it does not need any matter or material to carry its energy along. This means that light can travel through a vacuum? a completely airless space. (Sound, on the other hand, must travel through a solid, a liquid, or a gas.)

What happens when light passes from air into water?

Refraction of Light: as it passes from less dense to more dense mediums. When light passes from a less dense to a more dense substance, (for example passing from air into water), the light is refracted (or bent) towards the normal. The bending occurs because light travels more slowly in a denser medium.

What happens as a light wave bends when it passes from one medium into another?

The bending of light as it passes from one medium to another is called refraction. The angle and wavelength at which the light enters a substance and the density of that substance determine how much the light is refracted. The bending occurs because light travels more slowly in a denser medium.

What happens when light travels farther from its source?

Electromagnetic radiation behaves sometimes like a wave and sometimes like a stream of particles. What happens as light travels farther from its source? The intensity of light decreases as photons travel farther from the source. Produced by electrically charged particles and by changing magnetic fields.

What is transported by a wave?

Waves involve the transport of energy without the transport of matter. In conclusion, a wave can be described as a disturbance that travels through a medium, transporting energy from one location (its source) to another location without transporting matter.

What is transferred when a wave disturbs the material through which it travels?

Waves can transfer energy over distance without moving matter the entire distance. For example, an ocean wave can travel many kilometers without the water itself moving many kilometers. The water moves up and down—a motion known as a disturbance. It is the disturbance that travels in a wave, transferring energy.

How do prisms interact with light?

White light entering a prism is bent, or refracted, and the light separates into its constituent wavelengths. Each wavelength of light has a different colour and bends at a different angle. This prism transmits waves vibrating in one direction only and thus produces a plane-polarized beam from ordinary light.

What happens when sunlight is passed through a prism?

As light passes through a prism, it is bent, or refracted, by the angles and plane faces of the prism and each wavelength of light is refracted by a slightly different amount. As a result, all of the colors in the white light of the sun separate into the individual bands of color characteristic of a rainbow.
