The wavelength is the length that it takes a wave to complete one cycle (measured between any two peaks or troughs that are next to each other).
More energetic light has a SHORTER wavelength, so that's not what we want.
But frequency is a measure of how long it takes for a wave to complete one cycle, or how many wavelengths pass in a certain time. We usually use one second, so the unit is
.
Logically, shorter wavelength means that more waves pass in a second. (We deduce that frequency and wavelength are inversely proportional.)
So, more energy = shorter wavelength = greater frequency, so the answer is B.

Answer:
The force on each charge is 2668 N and the direction of force on each charge is towards the other charge. Which means force of attraction is there between the charges.
Step-by-Step Explanation:
Let the two charges be q1 and q2
q1 = 3.65*10^(-4) C
q2 = -3.65*10^(-4) C
Distance = d = 0.67 m
We know that the magnitude of the electric force that a particle exerts on another particle is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
Also, opposite charges attract each other.
Let F12 is the force on charge 1 by charge 2.
Let F21 is the force on charge 2 by charge 1.
F12 = F21 = F = kq1*q2/d^2 where k = 8.99*10^(9) N m^2 C^(-2)
