  1. AWhich one of the following phenomena supports Darwin's concept of natural selection in organic evolution?
  2. BWhich one of the following phenomena supports Darwin's concept of natural selection in organic evolution?
  3. CWhich one of the following phenomena supports Darwin's concept of natural selection in organic evolution?
  4. DWhich one of the following phenomena supports Darwin's concept of natural selection in organic evolution?

Correct answer

C. Which one of the following phenomena supports Darwin's concept of natural selection in organic evolution?

Step-by-step solution

From Einstein's photoelectric equation, hν=hν0+12mv2hν = h{ν}_{0} + \dfrac{1}{2}m{v}^{2}

Now, there is a frequency intercept along the positive horizontal axis and the slope of the graph between velocity and frequency is decreasing.
