Equation gives the relation between the angle of deviation d of a light ray incident on
Question:
Equation gives the relation between the angle of deviation фd of a light ray incident on a spherical drop of water in terms of the incident angle θ1 and the index of refraction of water.
(a) Assume that nair = 1, and differentiate фd with respect to θ1.
(b) Set dфd/dθ1 = 0 and show that the angle of incidence θ1m for minimum deviation is given by
And find θ1m for water, where the index of refraction for water is 1.33.

Using a few basic physics principles, you can impress your friends with a trick that makes a bottle disappear. For this experiment, you will need a mini plastic bottle, glycerin, a glass, and a funnel. First, open the bottle and pour some glycerin into it, then close the bottle tightly. Next, pour some water into the glass using a funnel. Place the mini bottle into the glass of water and it will look normal. This is because light travels through air faster than it travels through the glass and water, allowing our eyes to see the bottle inside the glass. However, when you fill the mini bottle with more glycerin, and pour glycerin into the glass, then put the glycerin filled bottle into the glass with glycerin in it. Half of the bottle that is submerged in the glycerin will become invisible as the light travels through glass and glycerin at the same speed, thus it does not bend and no refraction takes place, making the bottle invisible. This happens because both glass and glycerin have almost the same refractive index, which causes the speed of light to be the same in both mediums, causing no bending of light and making the bottle disappear.
