Answer:
option E
Explanation:
The correct answer is option E
Writing the relation between wavelength and frequency
f is the frequency
v is the velocity of wave
λ is the wavelength
From the above expression we can clearly see that frequency is inversely proportional to wavelength.
When the distance between the two successive crest is decreased then wave length of the wave also decrease.
If wavelength of the wave decreases then frequency of the wave increase.
hence, we can say that both wavelength and the frequency changes.
