Question

1. What is the wavelength of a wave that has a velocity of 220 m/s and a frequency of 660 Hz?

answer?????

2. What is the frequency of a wave that has wavelength of 0.25 meters and a velocity of 250 m/s?

answer????

Answer 1

question no1)
wavelength=velocity÷frequency
wavelength=220÷660
wavelength=0.3m.

question no 2)
frequency=velocity÷wavelength
frequency=250÷0.25
frequency=1000Hz.
