Options

  1. ARead the following Assertion and Reason and choose the correct option. Assertion: The species diversity decreases as we
  2. BRead the following Assertion and Reason and choose the correct option. Assertion: The species diversity decreases as we
  3. CRead the following Assertion and Reason and choose the correct option. Assertion: The species diversity decreases as we
  4. DRead the following Assertion and Reason and choose the correct option. Assertion: The species diversity decreases as we

Correct answer

A. Read the following Assertion and Reason and choose the correct option. Assertion: The species diversity decreases as we

Step-by-step solution

An electron will be emitted only when the frequency of light is more than the threshold frequency. As the frequency increases, K.E will increase linearly. The graph will be a straight line not passing through origin hence this is not a correct representation. So, this is the correct option.
Which of the graphs shown below does not represent the relationship between incident light and the electron ejected
The number of emitted electrons will depend upon the number of the photons but not on the energy and frequency of the photons.
