Card 1 of 24
From which line are angles of incidence, reflection and refraction measured?
A
A colour filter can only transmit wavelengths already present in the incident light.
B
Yes - each ray obeys i=ri=ri=r at its local normal.
C
A ray travelling along the normal has i=0∘i=0^\circi=0∘ and follows the same path after reflection.
D
From the normal.
