# Light with a frequency of $5.80 \times 10^{14}$ Hz travels in a block of glass that has an index of refraction of 1.52. What is the wavelength of the light (a) in vacuum and (b) in the glass?

## a) $$517 \mathrm{nm}$$b) $$340 \mathrm{nm}$$

welcome to the problem. Number thirty three point four. So this is chapter thirty three. In this question, we are given light with how infrequency equal so five point eight Jiro into tender, so affording hurt and it travels into the block off blood. So we had a broken glass here, and that has in next off reflection comes to one five to. So we need to find the wavelength of the light in the vacuum as well as in the class. So we will use this form here. So we have lambda. No. Is it close to see over F, which is, of course, with trained hundreds about eight ten per second or more Frequency, which is close to five point eight into dentist, about fourteen art. So this gives us five one seven men in return. So this is a reverent off light Have influenced this in a vacuum. This was but a Now go to the party. So we need to find the vein blend in glass. We have lam very close to land or not. What to this gives self five seven two nanometer or what? One point five. Excuse us. Three. Forty. Mental. Yeah. So this is the answer of this question. Thank you for watching
