Exploring Light Phenomena: Diffraction and Interference

What happens when a red laser of wavelength 633 nm passes through three sets of double slits?

a) Diffraction. b) Polarization. c) Interference. d) Dispersion.

Final Answer:

When a red laser of wavelength 633 nm passes through three sets of double slits, it results in the phenomena of diffraction and interference.

Explanation:

When a red laser light with a wavelength of 633 nm illuminates three sets of double slits, it results primarily in two phenomena: diffraction and interference. Diffraction is described as the bending of a wave around obstacles or through openings, which happens notably when the light passes through narrow slits. Each of the narrow slits in the double slit setup serve as sources of waves that spread out, bend, and overlap with each other.

The second phenomenon, interference, will occur as a result of this overlapping. Constructive interference creates the bright regions in the pattern when the waves combine to have larger amplitude, while destructive interference causes the dark regions where the waves cancel each other out. This alternating pattern of bright and dark regions is termed the interference pattern.

While the other options like polarization and dispersion are also phenomena related to light, they are not directly induced by the passage of light through double slits in this context.
