Question

Consider the following statements:
Statement 1: No sound can be heard on the surface of the moon.
Statement 2: Temperature of the surface of the Moon is very high and hence sound waves cannot be produced.
Choose the correct options.

• A. same direction
• B. perpendicular direction
• C. either A or B
• D. neither A or B

Answer 1

The correct option is A

same direction

Sound waves are longitudinal waves and require a medium to travel. On the moon, there is no atmosphere and hence there is no medium to propagate the vibrations produced. Thus, statement 1 is correct and statement 2 is incorrect.
