How is wavelength measured?

• In hertz

• In decibels

• In meters

What does a higher frequency indicate about a wave's speed?

• It's more powerful

• It's unchanged

• It moves slower

• It moves faster

How does frequency affect the wavelength of a wave?

• Higher frequency, shorter wavelength

• Frequency has no effect on wavelength

• Higher frequency, longer wavelength

• Lower frequency, shorter wavelength

If two waves have the same frequency, how do they differ in sound?

• They have different tones

• One is louder than the other

• They sound exactly the same

• They have different speeds

Between two waves with different frequencies, which has a lower tone?

• 16 hertz

• 30 hertz

• 5 hertz

• 130 hertz

What effect does a higher frequency have on a wave's tone?

• Makes it higher

• Makes it quieter

• Makes it lower

• No effect
