Compared to ultraviolet light, an electromagnetic wave that has a higher frequency will also have ________.
Nikitich [7]
  • The answer is shorter wavelength and equal speed.                        

That is, compared to ultraviolet light, an electromagnetic wave that has a higher frequency will also have shorter wavelength and equal speed.

This can be seen by the reaction given below:

 h\times \upsilon =\frac{c}{\lambda }

h= Planck's constant

c=speed of the light

 \upsilon=frquency

{\lambda }=wavelength

So, higher is the frequency, lesser is the volume while speed remains constant as c is speed of light.
