Example Question #652 : High School Physics

A saxophone plays a B-flat at  in normal air at . What is the wavelength of the note?

Possible Answers:

Correct answer:

Explanation:

Remember that the velocity of a wave is always equal to the wavelength times the frequency:

All sound waves will travel with the same velocity, the speed of sound. Using this value and the given frequency, we can calculate the wavelength.

Example Question #32 : Waves, Sound, And Light

A flute plays a note with a frequency of . What is the period of this note?

Possible Answers:

Correct answer:

Explanation:

Period is the inverse of frequency:

.

Given the frequency, we simply need to take the reciprocal in order to find the period.
