An underwater device directs ultrasounds of frequency 75 KHZ towards water surface. What is the wavelength of sound in the air above the water surface andwhat is its frequency? Speed of sound in air = 340m/s.

frequency = 75 KHz or 75000 Hz
velocity of sound in air = 340 m/s
wave length = velocity/ frequency
= 340/ 75000
= 0.004
velocity of sound in air = 340 m/s
wave length = velocity/ frequency
= 340/ 75000
= 0.004

frequency = 75000 Hz
velocity of sound in air = 340m/s
wave length = velocity / frequency = 340/75000 = 0.004
= 0.01m
velocity of sound in air = 340m/s
wave length = velocity / frequency = 340/75000 = 0.004
= 0.01m
