What is the wavelength of a light wave with a frequency of 2.5 × 1014 hz? a. 7.5 × 10-6 m b. 1.2 × 10-6 m c. 1.2 × 10-5 m d. 8.3 × 105 m

The right option is B

Explanation:

The frequency of the wave is given by the following formula:

where,

f = frequency of the wave.

c = speed of the light.

λ = wavelength of the light.

Therefore the correct option is B.

its going to be mutualism cuz they both benefit from the relationship.
