The wavelength of a wave refers to the horizontal distance that is travelled by a wave.
<h3>What is wavelength?</h3>
The wavelength of a wave is given by the formula;
v =λf
f = v/λ
Substituting the values;
f = 3 * 10^8 m/s/410 * 10^-9 m
f = 7.3 * 10^14 Hz
for 2
f = 3 * 10^8 m/s/434 * 10^-9 m
f = 6.9 * 10^14 Hz
for 3
f = 3 * 10^8 m/s/486 * 10^-9 m
f = 6.2 * 10^14 Hz
for 4
f = 3 * 10^8 m/s/657 * 10^-9 m
f = 4.6 * 10^14 Hz
