Answer:
When light incident at angle more than critical angle then whole beam of light will get reflected at same angle into the same medium
So correct answer is
Option D
Explanation:
Critical angle is the maximum angle of incidence for which light shows the phenomenon of refraction of light
Here light bends at 90 degree angle when light incident at critical angle
Now if the incident light is more than the critical angle then light will follow the rules of reflection and all light rays will get reflected at same angle as that of angle of incidence
So here we can say that correct answer is
Option D
Answer:
Part a)

Part B)

Explanation:
Part A)
At the top of the hump the force on the rider is
1) Normal force
2) weight
so here we know that




Part B)
At the top of the loop we will have

in order to remain in contact the normal force must be just greater than zero
so we will have
