When ultraviolet radiation is incident on a surface, no photoelectrons are emitted. If a second beam causes photoelectrons to be ejected, it may consist of
View answer and explanation
Correct option: B
X-rays
Option B (X-rays) is correct because X-rays have higher energy and frequency than ultraviolet radiation, allowing them to eject photoelectrons when UV radiation fails.
