If the voltage across the filament is increased, the cutoff wavelength

A

will increase

B

will decrease

C

will remain unchanged

D

will change

Text Solution

Verified by Experts

The correct Answer is:
C
The cut off wavelength depends on the accelerating potential difference which is unchanged. Hence, the wavelength will remain unchanged.
