In air, a sound wave with a frequency of 200 Hz has a wavelength of about 1.5 meters. What is the wavelength of a wave if the frequency is increased to 600 Hz?

see below

Explanation:

first of all, you find the speed of sound in air

which is

speed = frequency x wavelength

so

speed = 200 x 1.5

speed = 300 m/s

speed remains the same in the same medium

so you can use speed and frequency to find wavelength

speed = frequency x wavelength

300 = 600 x wavelength

wavelength = 0.5 m
