A concave lens is used to form an image. The diagram shows three incident rays that pass the object and then reach the lens. How
does the lens affect the blue ray, which is incident on a path headed to the focal point on the right?
A. The ray bends outward on a path that traces back to the focal point on the left.
B. The ray bends so that it emerges from the lens travelling parallel to the axis.
C. The ray continues on its path and travels through the focal point on the right.
D. The ray bends outward on a path that traces back to the vertex of the lens.

Answer:
The length of the stick is 0.28 m.
The time the stick take to move is 0.97 ns.
Explanation:
Given that,
Relative speed of stick v= 0.96 c
Speed of light
Proper length of stick = 1 m
We need to calculate the length of the stick
Using formula of length
Put the value into the formula
We need to calculate the time the stick take to move
Using formula of time
Put the value into the formula
Hence, The length of the stick is 0.28 m.
The time the stick take to move is 0.97 ns.
