Knowledge Check

  • Assertion : The blue colour of sky is on account of scattering of sun light. Reason : The intensity of scattered light varies inversely as the & fourth power of wavelength of the light.

    A
    If both assertion and reason are true and\ reason is a correct explanation of the assertion
    B
    If both assertion and reason are true but the reason is not a correct explanation of assertion.
    C
    If assertion is true but reason is false.
    D
    If assertion is false but reason is true

  • Assertion(A): The kinetic of the photo electron ejected increases with increases in intensity of incident light. Reason(R): Increase in intensity of incident light increases the rate of emission.

    Scattering OF Light

    Assertion (A): Sky predominantly appears light blue on account of scattering of light. Reason (R): Wavelength of blue light is least.

    Statement : Monochromatic X-rays fall on lighter elements such as carbon and show scattering and effect is known as Compoton effect . Explanation : lambda scattered light is always lower than lmbda incident light .

    Assertion (A): Scattering of light is the reflection of light from an object in all directions. Reason (R): The colour of scattered light depends on the size of scattering particles and wavelength of light.

    If a is the size of scatterer and lamda is the wavelength of light then Rayleigh law of scattering is valid for
