Question

When radiations of wavelength λ1 and λ2 are incident on certain photosensitive, such that E1 > E2 . Then Planck's constant 'h' is ......................... .

(C = Velocity of light).

  1. `((E_1 - E_2)(lambda_1 - lambda_2))/(C(lambda_1 * lambda_2))`
  2. `((E_1 - E_2)lambda_1C)/((lambda_1 - lambda_2)lambda_2)`
  3. `((E_1 - E_2)lambda_1lambda_2)/(C(lambda_2 - lambda_1))`
  4. `((lambda_1 - lambda_2)C)/((E_1 - E_2)lambda_1 * lambda_2)`

Solution

 

  1. `((E_1 - E_2)(lambda_1 - lambda_2))/(C(lambda_1 * lambda_2))`
  Is there an error in this question or solution?
