Refraction occurs when

• light bounces off an object, changing direction

• light bends as it passes from one medium to another

• light is absorbed by an object

• Never! Light is never refracted!

Light waves do NOT need a medium to travel.

• True

• False

When I speak in a high-pitch voice, the sound waves have

• high amplitude

• low amplitude

• high frequency

• low frequency

5.6.a

Frequency and Wavelength have inverse (opposite) relationships!

• True

• False

Waves with a low frequency must have

• low amplitude

• long wavelength

• short wavelength

• low energy

To decrease the amplitude, I should

• draw shorter waves

• draw "smaller" waves

• draw less waves

• draw waves with a longer wavelength
