Answer:
A. The wavelength increase
Explanation:
The wavelength should increase if the frequency of a sound increases.
??? (Sorry if this is wrong)
As white light passes through a prism, the light is separated into the different colours of light that we see and this is called the visible spectrum. Each colour of light has a different wavelength. The wavelength is inversely proportional to the energy of that light. As the wavelength increases, the energy decreases and vice-versa. The relationship is:
E = h/λ, E is energy, h is Planck's constant, and λ is the wavelength.
Therefore, the answer is B) different amounts of energy in white light.
Because it helps the environment strive and keep its self alive my controlling populations and bringing in new ones
