Which part of the electromagnetic spectrum has a lower frequency than visible light?

x-rays

infrared

gamma rays

ultraviolet

infrared

Explanation:

Electromagnetic spectrum w.r.t. increasing frequency is

Radio waves

Microwaves

Infra red

visible

ultra violet

x rays

gamma rays

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
