Question 1.
What is the definition of wavelength?
Show hintHide hint
Think about how you measure distance in the wave.
Question 2.
True or False: Wavelength influences the pitch of a sound.
Show hintHide hint
Consider how frequency relates to pitch.
3Question 3.
What is wavelength?
- The height of a wave
- The distance between two consecutive points in phase
- The time taken for a wave to pass a point
Show hintHide hint
Think about how you measure the distance of a wave.
4Question 4.
True or False: As wavelength increases, frequency must also increase.
- True
- False
Show hintHide hint
Consider the wave formula linking speed, frequency, and wavelength.
Question 5.
A musician plays a note at a frequency of 523 Hz. If the speed of sound is 343 m/s, calculate the wavelength of the note being played.
Show hintHide hint
Use the wave speed formula to solve.
Question 6.
Sound travels through steel at a speed of about 5960 m/s. If a sound has a wavelength of 0.65 meters, what is its frequency?
Show hintHide hint
Use the wave equation but rearranged to find frequency.
