Step-by-step explanation:
Quotient' means you will divide the numbers.
Also, to be 'no greater' means to be 'less than or equal to'.
The Planck–Einstein relation

gives that E, the photon energy, is equal to h, Planck's constant, times <span>ν</span>, the frequency.
We can solve the equation in terms of frequency to get

We substitute our given energy,

, and Planck's constant,

.
