Avery small red laser pointer is pointed on the wall across the room. when inspecting the reddish light on the wall, you notice that it is because it has been diffracted. a) bent b) brighter c) spread out d) bounced back

Diffraction is the spreading out of waves as they go through an opening or around a corner. In this case, the spot on the wall is bigger than the light the came out of the laser because it spread out as it traveled across the room.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
