Explanation of Solution

Given:

The given electromagnetic waves are microwaves, red light, ultraviolet light, infrared light and gamma rays.

The wavelength of the given electromagnetic waves has given in table below.

    Electromagnetic wavesWavelength (m)
    Microwave  1×103to3×103
    Red light  6.2×107to8.0×107
    Ultraviolet light  3×108to4×107
    Infrared light  8×107to3×105
    Gamma ray  6×1013to1×1010

Conclusion:

From the above table, the electromagnetic waves from lowest to highest wavelength are

Gamma ray, Ultraviolet ray, Red light, Infrared light and Microwaves.

Answer to Problem 1QAP

The gamma ray has highest energy per photon and microwaves has lowest energy per photon.

Explanation of Solution

Introduction:

The energy per photon can be determined by Einstein's photo electric equation which is given by

  E=hcλ

Where ' E' is the energy, ' c' is the velocity of light, ' h' is plank constant and ' λ ' is the wavelength.

The energy is inversely proportional to the wavelength. As wavelength is more energy is less and vice versa.

The given electromagnetic waves are microwaves, red light, ultraviolet light, infrared light and gamma rays and the wavelength of the given electromagnetic waves has given in table below.

    Electromagnetic wavesWavelength (m)
    Microwave  1×103to3×103
    Red light  6.2×107to8.0×107
    Ultraviolet light  3×108to4×107
    Infrared light  8×107to3×105
    Gamma ray  6×1013to1×1010

So, in the given electromagnetic waves, the gamma ray has lowest wavelength. So, the energy per photon of gamma ray has highest value. The microwave has highest wave length so it has lowest energy per photon.

Conclusion:

Thus, the gamma ray has highest energy per photon and microwaves has lowest energy per photon.

The figure below shows, at left, a solid disk of radius R = 0.600 m and mass 75.0 kg. Tu Mounted directly to it and coaxial with it is a pulley with a much smaller mass and a radius of r = 0.230 m. The disk and pulley assembly are on a frictionless axle. A belt is wrapped around the pulley and connected to an electric motor as shown on the right. The turning motor gives the disk and pulley a clockwise angular acceleration of 1.67 rad/s². The tension T in the upper (taut) segment of the belt is 145 N. (a) What is the tension (in N) in the lower (slack) segment of the belt? N (b) What If? You replace the belt with a different one (one slightly longer and looser, but still tight enough that it does not sag). You again turn on the motor so that the disk accelerates clockwise. The upper segment of the belt once again has a tension of 145 N, but now the tension in the lower belt is exactly zero. What is the magnitude of the angular acceleration (in rad/s²)? rad/s²
