Have more energy than ultraviolet rays; x-rays radio waves; microwaves radio waves; visible light infrared rays; radio waves

Answer : The correct option is, Infrared rays; radio waves

Explanation :

Electromagnetic waves : It is a wave in which two vectors are vibrating mutually perpendicular to each other and in direction of the wave. The two vectors are electric field and magnetic field.

The gamma-rays, x-rays, ultraviolet-rays, infrared-rays, microwaves and radio-waves are the electromagnetic waves.

The increasing order of electromagnetic waves in terms of wavelength will be,

As,

According to the formula, the energy is inversely proportional to the wavelength. That means higher the wavelength, lower will be energy and vice-versa.

The decreasing order of electromagnetic waves in terms of energy will be,

Therefore, infrared rays have more energy than radio waves.

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures
