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
    $4 v_0`$

Answer

Correct option: B.
$2 v_0`$
B
