Question 1
1 / -0

In an electronic transition atom cannot emit

A
γ-rays

B
Infra red radiations

C
Visible light

D
Ultraviolet rays

Solution

Atomic transitions don’t have sufficient energy to produce gamma rays, as they require a large amount of energy.
Question 2
1 / -0

Statement I: Radiations of frequency 1050 Hz are incident on a photosensitive surface. Photoemission takes place but photoelectrons have zero energy.
Statement II: Energy of incident photon is equal to work function.

A
Both Statement 1 and Statement 2 are correct and Statement 2 is the correct explanation for Statement 1

B
Both Statement 1 and Statement 2 are correct but Statement 2 is not the correct explanation for Statement 1

C
Statement 1 is correct but Statement 2 is incorrect

D
Statement 1 is incorrect but Statement 2 is correct

Solution

If photoemission takes place but with zero energy then the energy of incident photon is equal to work function.

A
3

B
2

C
1
