HELP!!

How does the energy of ultraviolet radiation compare to the energy of microwaves?


UV radiation has less energy than microwaves, because UV radiation has a lower frequency.


UV radiation has more energy than microwaves, becuse UV radiation has a higher frequency.


Microwaves have less energy than UV radiation, because microwaves have shorter wavelengths.


Microwaves have more energy than UV radiation, because microwaves have longer wavelengths.

Answer:

UV radiation has more energy than microwaves, because UV radiation has a higher frequency.

Explanation:

The energy of the electromagnetic radiation is given as:

[tex]E=hf\textrm{ or }E=\frac{hc}{\lambda}[/tex]

Where,

[tex]h\rightarrow\textrm{Planck's constant}\\c\rightarrow\textrm{Velocity of light}\\f\rightarrow\textrm{frequency of radiation}\\\lambda \rightarrow\textrm{wavelength of radiation}[/tex]

Now, we know from electromagnetic spectrum that, frequency of UV radiation is much higher than that of microwaves.

From the energy equation of the electromagnetic radiation, we conclude that:

Energy is directly proportional to frequency of radiation but inversely proportional to its wavelength.

As UV radiation's frequency is higher, it will have more energy than microwaves.
