Why can light travel through outer space, but sound cannot?

Sound has vibrations of molecules and it spread through the air

Explanation: Pretty much what this means you need molecules to produce sounds and in space there isn't any. On the other hand light is a electromagnetic waves and those waves do not need a medium to travel through

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
