To solve this problem it is necessary to apply the concepts related to Wavelength depending on the frequency and speed of light.
The equation that meets these parameters is given by

Where,
c = Speed of light

f = Frequency
Our values are given as
velocity of light in free space
f = 2Hz
Replacing we have that

Therefore the correct answer is B.

Nuclear energy is EXTREMELY ecofriendly, punching down any fossil fuels and even wind energy. It also is reliable, and has low emissions. However, nuclear energy is somewhat expensive and can go wrong, being dangerous to the environment and people. Along with this, uranium is finite and radioactive waste disposal is really bad.
Acceleration is the speed of an object speeding up
Whether it is velocity or just speed
