7. Two beams of light are incident on the same spot on a wall. Each beam comes from an independent robot. Does this create a superposition pattern on the wall?
8. Parallel light rays from a blaster are incident on a flat mirror. Can the rays reflected from the mirror converge on a single point? Explain your answer.

Answer #1

7)

NO  

condition for  superposition pattern

phase difference between two wave must be constant with time or simply they must come from a coherence source but in this case they are independent so not possible to full this condition

Two sources are said to be coherent if they have exactly same frequency, and have zero or constant phase difference.

8.

NO

because light reflected from a flat mirror bounce back at same angle at which they fall on mirror  

so if two parallel ray fall on mirror after reflection they will bounce back   parallel to each other

see this figure

A Gaussian laser beam is incident on the interface between two dielectric media with refractive indices of n1=2 and n2=1.5. a) If the beam is at normal incidence to the interface and its waist location coincides with it, what is the reflection coefficient? If the spot size is 0.5μm, plot the reflected energy in percentage vs. wavelength from 300nm – 800nm. b) If the wavelength is fixed at 630nm and the waist diameter is still 0.5μm, but incident angle gradually...

Snell's Law and the Law of Reflection explain how light is redirected when it encounters a surface between two media. In the extreme, light may only reflect at a boundary, and go back into the medium it was in. More often, some of it reflects and some goes through. If the boundary is plane and flat, then these laws are easy to interpret. When the boundary is curved, they describe happens at every point on the surface. One of the...
