Question
A 1000 Hz sound wave in air strikes the surface of a lake and penetrates into water. If speed of sound in water is 
,the frequency and wavelength of waves in water are
- 1500 Hz, 1m
- 1000 Hz, 1.5m
- 1000 Hz, 1m
- 1500 Hz, 1.5m
The correct answer is: 1000 Hz, 1.5m
Frequency remains the same 
wavelength chances
