Waves #2

Front

What is the longest wavelength of visible light?

Back

Red light has the longest wavelength in the visible spectrum.

Front

How does the amplitude of a wave affect its energy?

Back

Greater amplitude means more energy; less amplitude means less energy.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another.

Front

What color absorbs all visible light?

Back

Black absorbs all visible light.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive peaks of a wave.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as one increases, the other decreases.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second.

Front

What is reflection?

Back

Reflection is the bouncing back of light when it hits a surface.

Front

What is dispersion?

Back

Dispersion is the separation of light into its different colors.

Front

What is the difference between a transverse wave and a longitudinal wave?

Back

In a transverse wave, the motion is perpendicular to the direction of the wave, while in a longitudinal wave, the motion is parallel.
