When light is incident from air to glass at an angle 57^@ , the reflected beam is completely polarised. If the same beam is incident from water to glass, the angle of incidence at which reflected beam is completely polarised will be

Assertion: A quious gold colloidal solution is red in colour. Reason: The colour arises due to scattering of light by colloidal gold particles.

Statement-1 : On viewing the clear blue portion of the sky through a Calcite Crystal, the intensity of transmitted light varies as the crystal is rotated. Statement-2 : The light coming from the sky is polarized due to scattering of sun light by particles in the atmoshphere. The scattering is largest for blue light.

When a more intense beam of light is passed during photoelectric effect then :

Blue colour of the sky is due to a. Adsorption of light by dust particles b. Reflection of light by dust particles c. Scattering of light by dust particles d. Pressure of clouds which are a colloidal dispersion of water particles in air
