Physical The distance between a widening of the forest and a lens is 10 cm. If the lens power is 12.5 D. What type of image do you get? Can you solve it analytically and graphically?. Will the little d'anolyze see his image? Explain to me why the answer.

Now, a beam of light strikes at an angle of 30 degrees from the air on an acrylic plate floating over alcohol. If the refractive rate of alcohol is 1.36 and the acrylic refractive rate is 1.49, trace the ray march and calculate the angle at which the ray enters the alcohol, if it enters​
