| Assertion (A): The scattering of light while passing through a true solution is called Tyndall effect. |
| Reason (R): Intensity of scattered light is inversely proportional to the fourth power of wavelength. |
A) Both A and R are true and R is the correct explanation of A
B) Both A and R are true but R is NOT the correct explanation of A
C) A is true but R is false
D) A is false and R is True
Correct Answer: D
Solution :
| Option [d] is correct. |
| Explanation: When light is passed through a true solution does not occur. Scattering occurs when light is passed through a colloidal solution. So, the assertion is false. |
| In Rayleigh scattering intensity of scattered light is inversely proportional to the fourth power of wavelength, blue light is scattered mush more strongly than red light. Hence the reason is true. |
