Answer: High energy and Low wavelength.
Explanation: We are given an electromagnetic wave having high energy, so by using Planck's equation:
[tex]E=h\nu[/tex]
where, E = energy
h = Planck's constant
[tex]\nu[/tex] = frequency
here, Energy and frequency follow direct relation and hence high frequency means high energy.
and [tex]\nu=\frac{c}{\lambda}[/tex]
[tex]\nu[/tex] = Frequency
c = speed of light
[tex]\lambda[/tex] = wavelength
Here, the frequency is inversely related to the wavelength, hence high frequency means low frequency.
