Alight wave has a 670 {\rm nm} wavelength in air. its wavelength in a transparent solid is420 {\rm nm} .a)what is the speed of light in this solid? b)what is the light's frequency in the solid?

Explanation:

given,

Light wave wavelength in Air, λ_(vac) = 670 nm

wavelength in transparent solid, λ= 420 nm

Refractive index of the solid

   n = 1.6

a) speed of light in the solid

       v = 0.625 c

b) light's frequency in the solid

frequency of light remain same when light move from one medium to another.

 f is the frequency of light

        f = 4.47 x 10⁻¹⁴ Hz

the light's frequency in the solid is equal to 4.47 x 10⁻¹⁴ Hz

i was thinking more like reflects green light, just not sure

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
