Question

Determine how many wavelengths will fit into the glass container when it is a vacuum. Since the light passes through the container twice, you need to determine how many wavelengths will fit into a glass container that has a length of 2L.

Answer 1

# = 2L /λ

Step-by-step explanation:

For this exercise we can use a direct proportion rule. If there is 1 wave in 1 wavelength in 2L wave how many lengths are there

# = 2L /λ 1 wave

let's calculate

# = 2L /λ

we see that the longer the wavelength the fewer waves fit in the container
