thank you so much for your help!

so it passes L-d with speed c first so t1 is (L-d)/c and after this it passed d with speed v so t2 is d/v?

i do not understand what you mean, i only have the information in the question so dt = t2 -t1. I do not have numbers

Homework Statement In a physics lab, light with a wavelength λ0 travels in vacuum from a laser to a photocell in a time t1. When a slab of glass with a thickness d is placed in the light beam, with the beam incident along the normal to the parallel faces of the slab, it takes the light a time...
