Sound and Light Waves Practice

As the fire truck approached Mary, the pitch of the siren got higher. Once the fire truck passed and moved away, the siren's pitch got lower. This change in pitch is because of a change in the sound wave's

• concussion. 
• amplitude. 
• reflection.
• frequency. 

If the distance represented by the letter A were increased, how would it change the way the sound was heard?

• The sound would be higher. 
• The sound would be lower. 
• The sound would be softer. 
• The sound would be louder.

When comparing the two waves that are shown, how would Wave A (green wave) differ than Wave B (black wave)?

• Wave A and B have the same amplitude, but wave B (black) has a lower pitch.
• Wave A and B have the same amplitude, but Wave A has a lower pitch. 
• Wave A and B have the same pitch, but Wave A is a softer sound. 
• Wave A and B have the same pitch, but Wave B is a softer sound.

A wave that requires a medium through which to travel

• mechanical wave
• chemical wave
• electromagnetic wave
• pitch

Highest point of a wave

• crest
• trough
• wavelength
• frequency

The shorter the wavelength the
