Question

Find the best statement which explains how time slows down at high speeds?

• A. At high speeds, light must travel a greater distance to create the same repeating event.
• B. At high speeds, light travels a shorter distance to create the same repeating event.
• C. The speed of light is relative to time.
• D. The speed of light is not relative to frame of reference.
• E. All of the options are needed to explain how time slows down relative to speed.

Answer 1

Answer: (D)

The speed of light is not relative to frame of reference.

At high speed the light will move with its constant velocity of $3\times {10}^{8}m/s$, The frame is moving with a velocity almost equal to the velocity of light, but the distance travelled by the light is same from any frame. The speed of light is relative to time.
