A hydrogen discharge lamp emits light with two prominent wavelengths: 656 nm (red) and 486 nm (blue).
Question:
A hydrogen discharge lamp emits light with two prominent wavelengths: 656 nm (red) and 486 nm (blue). The light enters a flint-glass prism perpendicular to one face and then refracts through the hypotenuse back into the air. The angle between these two faces is 35?.a. Use Figure 35.18 to estimate to ?0.002 the index of refraction of flint glass at these two wavelengths.
b. What is the angle (in degrees) between the red and blue light as it leaves the prism?
n increases as A decreases. n 1.62 1.60- Flint glass 1.58 - UV 1.56 IR 1.54 - 1.52- Crown glass 1.50 + A (nm) 800 300 400 500 600 700

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.
