1 Jamaal has done an experiment using a mirror to
investigate how light is reflected.
He measures the angle of incidence and the
angle of reflection. Here are his results plotted
on a graph
a Which result or results should be repeated?

angle of incidence
b Why?
c Where should Jamaal draw a line of best fit?
d How do his results demonstrate the law of reflection? Explain your answer.
e He replaces the mirror with a white screen. The reflected ray is very faint. Why?​

Answer 1

Answer:

I think u have to solve by urself

Answer 2

Answer:

a) 40

b) because it's not accurate

c) at the middle of the reflection angel and incidence angle

d) the angle of reflection is equal to angle of incidence

e) because it is not transparent
