Exit Check 7.1 Intro to Waves

7.1.3

A trombone player slides from a note with a high frequency to one with a low frequency. What happens to the wavelength of the sound wave as the frequency gets lower?

• The wavelength gets longer

• The wavelength gets shorter

• The wavelength doesn't change but the wave moves slower

• The wavelength doesn't change but the wave moves faster.

Answer explanation

This question links to success criteria 7.1.3: I can describe the relationship between wave speed, wavelength and frequency and use this relationship to determine missing values.

If you got it correct place a check mark in the question results section. If you got it incorrect place an X in that section. If this was a redemption question, cross out the one X and replace it with a check mark.
