Question

Emitted at right angles to each other

Options:
A. "When emitted at right angles, waves demonstrate constructive interference."
B. "Emitted at right angles, waves exhibit destructive interference."
C. "The emission of waves at right angles results in diffraction patterns."
D. "Waves emitted at right angles manifest as standing waves."

Answer 1

When light passes through narrow slits, it is diffracted into semicircular waves. The interference of these waves can result in either constructive or destructive interference. The angles of interference depend on the wavelength and distance between the slits.

Step-by-step explanation:

When light passes through narrow slits, it is diffracted into semicircular waves. Pure constructive interference occurs where the waves are crest to crest or trough to trough, while pure destructive interference occurs where they are crest to trough. The light must fall on a screen and be scattered into our eyes for us to see the pattern. These angles of interference depend on the wavelength and distance between the slits.
