Hello:)! I don’t really understand the uniform deceleration too :/
1 answer:
Answer:
Deceleration is the opposite of acceleration.
The mathematical formula for deceleration is:
Uniform deceleration of an object can be defined as decreasing the velocity of an object in equal amount in an equal interval of time.
The graph attached below shows a constant decrease in the velocity with a uniform time interval.

Answer:
(a)
(b)
(c)
(d)
Solution:
As per the question:
Refractive index of medium 1,
Angle of refraction for medium 1,
Angle of refraction for medium 2,
Now,
(a) The expression for the refractive index of medium 2 is given by using Snell's law:
where
= Refractive Index of medium 2
Now,
(b) The refractive index of medium 2 can be calculated by using the expression in part (a) as:
(c) To calculate the velocity of light in medium 1:
We know that:
Thus for medium 1
(d) To calculate the velocity of light in medium 2:
For medium 2:
