Question

Assertion :In the visible spectrum of light, red light is more energetic than green light. Reason: The wavelength of red light is more than that of green light.

• A. Assertion and Reason are individually true and Reason is the correct explanation of Assertion.
• B. Assertion and Reason are individually true but Reason is not the correct explanation of Assertion.
• C. Assertion is true, but Reason is false.
• D. Assertion is false, but Reason is true.

Answer 1

The correct option is D Assertion is false, but Reason is true.

Energy of light is given by $E=\frac{hc}{\lambda }$
Since wavelength of red light is more than that of green light, so red light has less energy than that of green light.
So assertion is falsebut reason is true.
