Question

Assertion (A): In the pure spectrum, each colour is separated with the other colour, i.e., there is a sharp boundary line separating the colours.

Reason (R): Different colours have different width on the screen.

Options

• Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion.

• Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion.

• Assertion (A) is false, but Reason (R) is true.

• Assertion (A) is true, but Reason (R) is false.

Answer 1

Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion.

Explanation:

Both statements are true. A pure spectrum has sharp boundaries between its colours, and the colour bands can have different widths on the screen. The difference in width does not explain why the boundaries are sharp.
