2.3 Waves, Sound and Light Energy Review

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, which includes visible light, radio waves, X-rays, and more, organized by wavelength.

Front

What happens to light when it passes through a prism?

Back

When light passes through a prism, it is refracted and separated into its component colors, creating a visible spectrum.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, caused by a change in its speed.

Front

How does sound travel through different media?

Back

Sound travels faster through solids (like steel) than through liquids (like water) and gases (like air) due to the density and elasticity of the medium.

Front

What is reflection?

Back

Reflection is the bouncing back of light waves when they hit a surface, such as a mirror.

Front

What is the speed of sound in air compared to steel?

Back

Sound travels faster in steel than in air due to the closer arrangement of particles in solids.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What are the two main types of waves?

Back

The two main types of waves are mechanical waves (which require a medium, like sound waves) and electromagnetic waves (which do not require a medium, like light waves).

Front

What is the normal line in refraction?

Back

The normal line is an imaginary line perpendicular to the surface at the point of incidence where light enters a new medium.

Front

What is the visible spectrum?

Back

The visible spectrum is the portion of the electromagnetic spectrum that can be seen by the human eye, typically ranging from red to violet.
