5. The critical angle is 40°at the interface from plastic to air. Figure 11 shows a light ray is incident on the top surface of the plastic block. Draw on Fig. 11 the ray path inside the plastic block until it emerges from the block. All the refraction and reflection angles should be drawn to scale using a protractor 15 Air Plastic Figure 11

Partner: Date Name 11 Snell's Law Introduction When light passes from one material to another it is always bent away from its original path. This process is known as refraction and the change in direction depends on the change in optical density (or refractive index) of the two materials. A larger change in refractive index results in a larger change in angle between incoming and outgoing light beams. A light beam bends closer to the normal in the material with...

water interface (the surface of the lake), it is partly
reflected back into the air and partly refracted
or transmitted into the water. This explains why on the surface of
a lake sometimes you see the reflection of the surrounding
landscape and other times the underwater vegetation.
These effects on light propagation occur because light travels at
different speeds depending on the medium. The index of refraction
of a material, denoted by n, gives an indication of the speed of...

Calculate the frequency of monochromatic light of wavelength = 550 nm in a vacuum. What color is it?qb) Calculate the frequency, wavelength, and speed of this light inside a lens composed of glass having index of refraction n = 1.58.2) A ray of light (in air) enters the top of a glass plate at an angle of 35 from a line perpendicular to the surface. The refractive index of the glass is 1.48.a) Calculate the angle between the ray...

*- Jordi 1. 14 points. You wish to project an image of a slide onto a screen for a slide show. The slide is initially in a holder 0.0500m from the lens and the screen is 3.00m from the lens. The image is well-focused on the screen. a. Determine the focal length of the lens used to project the image. b. Is the lens converging or diverging? How do you know? c. If you instead want to use a screen...

Part I: Background When a ray of light strikes a smooth surface, it can either reflect, such as with a mirror, or it can both reflect and refract, such as with glass. In this make-up lab activity, we shall look at both situations. This make-up lab shall try to replicate the lab from your lab manual as best possible. Be sure to read the "Discussion" in your regular lab manual. You will be using the Bending Light simulation. Part II:...
