Answer 1

The wavelength of a wave refers to the horizontal distance that is travelled by a wave.

What is wavelength?

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
