MCQ
The threshold frequency for a certain photosensitive metal is $v_0`$. When it is illuminated by light of frequency $v = 2v_0`,$ the maximum velocity of photoelectrons is $"v"_0`$. What will be the maximum velocity of the photoelectrons when the same metal is illuminated by light of frequencyv = 5v"v"_0`?
- A$`sqrt2 "v"_0`$
- ✓$2 v_0`$
- C$`2 sqrt2 "v"_0`$
- D$4 v_0`$
