# Which has the greater energy, yellow light or green light?

Green light.

#### Explanation:

According to the Planck's equation,
$E = h \nu$
where,
$E =$ Energy of the light wave
$h =$ Planck's constant
$\nu =$ Frequency of the light wave
therefore E ∝ nu
So, higher the frequency, higher the energy. Hence, green light has more energy than red light.
