Question

Statement1: There is a time delay between the actual sunrise and the apparent sunrise.

Statement2: Since the earth is spinning on its axis, so it takes sunlight 4 minutes to travel from one longitude to another.

• A. statement 1 and 2 are correct but statement 2 is not the reason of statement 1
• B. Statement 1 and 2 are correct and statement 2 is the correct reason for statement 1
• C. Both statements are wrong
• D. Statement 1 is correct but statement 2 is incorrect.

Answer 1

The correct option is A

statement 1 and 2 are correct but statement 2 is not the reason of statement 1

Since we have an atmosphere which has a higher refractive index as compared to vacuum, the sunlight entering the atmosphere bends. So we see the apparent sunrise 2 minutes before the actual sunrise(the actual crossing of the sun with respect to horizon).
