Question

As the wavelength increases, the frequency (2 points) decreases and energy decreases. increases and energy increases. decreases and energy increases. increases and energy decreases

Answer 1

I TOOK THE TEST! the answer is INCREASES AND ENERGY INCREASES!

Answer 2

Bohr's equation for the change in energy is

`\Delta E= (hc)/(\lambda)`
where
h = Planck's constant
c == the velocity of light
λ = wavelength.

The velocity is related to wavelength and frequency, f, by
c = fλ

Let us examine the given answers on the basis of the given equations.

a. As λ increases, f decreases and ΔE decreases.
TRUE

b. As λ increases, f increases and ΔE increases.
FALSE

c. As λ increases, f increases and ΔE decreases.
FALSE

Answer:
As the wavelength increases, the frequency decreases and energy decreases.
