List of top Physics Questions on Electromagnetic Spectrum asked in AP EAPCET

The velocity of electromagnetic waves in vacuum is given by

The correct order of electromagnetic waves with increasing frequency is

Light with an energy flux of \(20 \, W \, cm^{-2}\) falls on a non-reflecting surface at normal incidence. If the surface has an area of \(25 \, cm^2\), then the total momentum delivered for complete absorption during a 15 minute time span is:

Which types of images are produced by X-rays?

The electromagnetic waves: Visible, ultraviolet, infrared, gamma rays, X-rays in increasing order of their wavelengths is:

The type of electromagnetic waves that are produced due to rapid acceleration and deceleration of electrons in aerials is:

Assertion (A): Microwave oven heats a food item containing water molecules most efficiently.
Reason (R): Resonant frequency of water molecules matches the frequency of microwaves generated by microwave oven.

Light falls normally on a non-reflecting surface. If the average force exerted on a surface with area \(15\,\text{cm}^2\) during \(20\) minute time interval is \(10^{-6}\,\text{N}\), then energy flux of light is \((c=3\times10^8\,\text{m s}^{-1})\)

The correct ascending order of the wavelengths of the following electromagnetic waves is: Ultraviolet, X-rays, Infrared, Gamma rays and Visible light.
