A ray of light has a wavelength of 284 nm in glass (n = 1.51). What is its wavelength in a vacuum? (Remember, the wavelength is longer in a vacuum.) (Unit = nm)​

the answer is in this

Explanation:

step-by-step explanation:

we are given

we have to simplify it

firstly, we will factor it

now, we can cancel like terms

now, we can combine it

so, we get
