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:
[tex]h\times \upsilon =\frac{c}{\lambda }[/tex]
h= Planck's constant
c=speed of the light
[tex] \upsilon[/tex]=frquency
[tex]{\lambda }[/tex]=wavelength
So, higher is the frequency, lesser is the volume while speed remains constant as c is speed of light.
