The earth is assumed to be a sphere of radius R. A platform is arranged at a height R from the surface of the earth. The escape velocity of a body from this platform is fv where v is its escape velocity from the surface of the Earth. The value of f is 1/2 1/3
Multiple Choice Options
- A both light and sound waves can travel in vaccum
- B both light and sound waves in air are transverse
- C The second waves in air are longitudinal while the light waves are transverse
- D both light and sound waves in air are
Step-by-Step Verified Solution
Light waves are electromagnetic waves. Light waves are transverse in nature and do not require a medium to travel, hence they can travel in vacuum. Sound waves are longitudinal waves and require a medium to travel. They do not travel in vacuum.
