Question 1:

Interference is the result of:

Explanation: Interference occurs when two or more waves superpose, resulting in the addition or subtraction of their amplitudes at different points in space.

Question 2:

Diffraction refers to the:

Explanation: Diffraction is the bending of waves around obstacles or the spreading out of waves when they encounter an opening or an edge.

Question 3:

Polarization of light refers to the:

Explanation: Polarization of light refers to the phenomenon where the oscillation of light waves occurs in a single plane, usually restricted to a specific direction.

Question 4:

The phenomenon of interference is observed in:

Explanation: Interference is commonly observed in experiments like Young's double-slit experiment, where light waves interfere with each other, creating a pattern of constructive and destructive interference.

Question 5:

Diffraction grating is a device that:

Explanation: A diffraction grating is a device with many closely spaced slits or rulings that can separate light into its component colors through the process of diffraction.
