How are the energy of infrared, visible light and ultraviolet rays related? and why? a) infrared contains the least energy and ultraviolet contains the most energy. the energy of a wave is proportional to its wavelength. b) infrared contains the most energy and ultraviolet contains the least energy. the energy of a wave is proportional to its wavelength. c) infrared contains the least energy and ultraviolet contains the most energy. the energy of a wave is inversely proportional to its wavelength. d) infrared contains the most energy and ultraviolet contains the least energy. the energy of a wave is inversely proportional to its wavelength.

The correct answer is Option C.

Explanation:

Energy of the Electromagnetic Spectrum is given by the Planck's equation:

Where,

E = Energy of the wave

h = Planck's constant

= Frequency of the wave

And we know that,

where,

c = Speed of light

= Wavelength of the wave

Putting the value of frequency in energy equation, we get:

From the above relation, we get that energy is inversely related to wavelength of the wave.

From the spectra, we know that order of wavelength follows:

Infrared > Visible > UV

So, the order of energy gets reversed and the order becomes:

Infrared < Visible < UV

From the above information, we conclude that the correct option is Option C.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
