Question

Compared to ultraviolet light, an electromagnetic wave that has a higher frequency will also have ________.

Answer 1

shorter wavelength and equal speed

(I took the test it is correct)

Answer 2

Answer: High energy and Low wavelength.

Step-by-step explanation: We are given an electromagnetic wave having high energy, so by using Planck's equation:

`E=h\\u`

where, E = energy

h = Planck's constant

`\\u` = frequency

here, Energy and frequency follow direct relation and hence high frequency means high energy.

and
`\\u=(c)/(\lambda)`

`\\u` = Frequency

c = speed of light

`\lambda` = wavelength

Here, the frequency is inversely related to the wavelength, hence high frequency means low frequency.
