Diffraction Experiment: What Pattern Will Be Projected?

What pattern will be projected on the screen in the setup described?

a) Circular pattern

b) Square pattern

c) Triangular pattern

d) No pattern

Final answer:

Answer:

The pattern projected on the screen through a triangular aperture will be triangular in shape and colorful due to the combination of green and red light diffraction.

In the setup described, with a small green light bulb above a small red light bulb and a triangular hole mask, the pattern projected on the screen will be a triangular pattern. This is due to the shape of the aperture through which the light passes. When light passes through an aperture, it undergoes diffraction, which causes the light to spread out. The resulting pattern on the screen typically corresponds to the shape of the aperture, which in this case is triangular.

Diffraction patterns can be more complex with additional effects such as interference when there are multiple light sources or slits, but if we are only considering a single triangular aperture, the pattern will be triangular. The color of the pattern will be a combination of the green and red lights, appearing as colorful in regions where both lights overlap on the screen. In areas where one of the colored lights does not reach, the pattern will be monochromatic.
