Physics Question on Wave characteristics
If a wave gets refracted into a denser medium, then which of the following is true?
A
Wavelength, speed and frequency decreases
B
Wavelength increases, speed decreases and frequency remains constant
C
Wavelength and speed decreases but frequency remains constant
D
wavelength, speed and frequency increases
Answer
Wavelength and speed decreases but frequency remains constant
Explanation
Solution
The correct option is (C): Frequency is independent of medium. For denser medium, wavelength and speed both would decrease
