QID 403329:
Question gives two different wavelengths of light and asks to compare their frequency. In this case, it is enough to know the relevant equation given that the speed of light is a constant and their relative wavelengths can be judged from v = (f)(lambda). Knowing this equation, this relationship, is essential to being able to recognize this pattern and, thus, to being able to answer the question correctly.

Give the equation for {{c2::velocity of a wave}}:
{{c1:: \(v = f*\lambda\)}}
{{c1:: \(v = f*\lambda\)}}
Extra
v = wave speed (m/s)
f = frequency (Hz)
λ = wavelength (m)
1) The "golden rule" explains the relationship between wave speed (v), wavelength (λ), and period (T) or frequency (f).
2) Recall that T = 1/f and f = 1/T.
3) Wave speed is determined by the distance a wave travels in one period, which is v = λ/T.
4) Since f = 1/T, we can also express wave speed as v = λf.
5) This relationship between wave speed, wavelength, and frequency is known as the "Golden Rule" for waves.
