Assertion (A) The colour of radiation does not change on passing through different media. Reason (R) The media do not absorb or emit colours.

Options

  1. ABoth AA and RR are true and RR is a correct explanation for AA.
  2. BBoth A\mathrm{A} and R\mathrm{R} are true but R\mathrm{R} is not a correct explanation for A\mathrm{A}.
  3. CAA is true but RR is false.
  4. DA is false but RR is true.

Correct answer

C. AA is true but RR is false.

Step-by-step solution

The colour of radiation does not change on passing through different media. This is because, when light radiation passes through different media, only wavelength and speed changes, but frequency remains same and colour of light radiation depends only on frequency. Hence, Assertion (A) is true. "The media do not absorb or emit colours" this statement is wrong. Because the absorption or emission of colours of radiation depends only on the nature of medium. Hence, Reason is false.
