(D) Diffraction​

Answer 1

Answer:

Compton effect

follo me and mark me brainalist please

Answer 2

Colours in thin films are because of B) Interference.

• Interference is the phenomenon where an increase or decrease in amplitude of combining waves occurs due to constructive or destructive interference respectively.it occurs due to the superposition of Lightwaves.
• Dispersion is the splitting of white light waves into higher and lower wavelengths of their constituent colours.
• Diffraction is the bending of light when it encountered any obstacle in its path.
• When electrons act upon electromagnetic rays such as x rays then there is an increase in wavelength it is known as the Compton effect.
