Q1:a) Parallel rays of green mercury light with a wavelength of 546 nm pass through a slit covering a len with a focal length of 60.0 cm. In the focal plane of the lens the distance from the central maximum to the first minimum is 10.2mm. What is the width of the slit?

In the figure, a 2.1-m-long vertical pole extends from the bottom of a swimming pool to a point 50.0 cm above the water. Sunlight is incident at angle = 51.0°. What is the length in meters of the shadow of the pole on the level bottom of the pool? The water has an index of refraction of 1.33. A Blocked sunrays

Building contractors often install double-glazed windows to prevent thermal energy (heat) from entering or exiting a building. In addition to being effective insulators, such windows present interesting optical effects. 62.0 mm In the figure, a double-glazed window consists of two identical of glass (ng panes 1.54), each yg thick, separated by an air gap of ya = 49.6 mm. Use na = 1.00 for the index of refraction of air. = If light incident on the glass makes an angle of = 40.00° with respect to the glass, find the shift in path Ax as the light enters the room. Ax = 42.36 Incorrect glass air glass mm

Stephen is given a large crystal and needs to verify whether it is a diamond or cubic zirconia. He shines a beam of light at a 48.8 ° angle upon the face of the crystal and measures the refraction angle. What is the refraction angle if the crystal is a diamond? refraction angle for diamond - What is the refraction angle if the crystal is a cubic zirconia? refraction angle for cubic zirconia =

A ray of white light strikes the surface of a 4.0-cm-thick slab of flint glass as shown. As the ray enters the glass, it is dispersed into its constituent colors. Estimate how far apart the rays of deepest red and deepest violet light are as they exit the bottom surface. Which exiting ray is closer to point P?
