Question

Question 6 Remember entering vary large or very small numbers: • For very large numbers: example 3 x 108 enter it as 3E8 • For very small numbers: example 6.626 x 10 34 enter it as 6.626E-34 Long wavelengths have Select an answer v frequencies and short wavelengths have Select an answer frequencies. Low frequency waves are Select an answer v energy waves. High frequency waves are Select an answer energy waves.

Answer 1

We know that

ν = c/λ

That is frequency is inversely proportional to wavelength

E = hv

That is energy is directly proportional to frequency

•Longer wavelengths have Low frequencies and short wavelengths have high frequencies

• Low frequency waves are Lower energy waves. High frequency waves are High energy waves.
