A light ray travelling in glass medium is incident on glass-air interface at an angle of incidence θ\theta. The reflected (R)(R) and transmitted (T)(T) intensities, both as function of θ\theta, are plotted. The correct sketch isA light ray travelling in glass medium is incident on glass-air interface at an angle of incidence θ .

Options

  1. AWhich one of the following statements is not true?
  2. BWhich one of the following statements is not true?
  3. CWhich one of the following statements is not true?
  4. DWhich one of the following statements is not true?

Correct answer

C. Which one of the following statements is not true?

Step-by-step solution

After critical angle reflection will be 100%100 \% and transmission is 0%0 \%. Options (b) and (c) satisfy this condition. But option (c) is the correct option. Because in option (b) transmission is given 100%100 \% at θ=0∘\theta=0^{\circ}, which is not true. Analysis of Question From examination point of view question is moderately difficult. Because it takes little time to understand the given graphs clearly.
