1. A piece of lucite (transparent plastic) has an index of refraction of 1.45. Find the critical angle (for total internal reflection) if the plastic is in air. Now find the critical angle if the plastic is immersed in water. In both cases, we are considering a ray of light inside the lucite, hitting the interface between lucite and air or lucite and water.

2 A mylar balloon has a shiny surface with a radius of curvature of 0.80 m. Suppose you look at the balloon, with your face 1.0 m from its surface. How far below the surface is the image of your face? Draw a ray-tracing diagram illustrating this situation. Make the draw TO SCALE AND ACCURATE, with a scale of 1.0 m = 10 cm (that is, 10 to 1 reduction.)

  • Light Refraction and Reflection of a Laser

    If the angle of incidence is equal to or exceeds the critical angle, there would be total internal reflection and the light ray would not be able to come out.

  • Prism, Internal reflection, Rainbow

    As this is larger than the critical angle, the light will suffer the total internal reflection and then incidents on the base perpendicularly (as shown in the diagram (i)). So this will emerge at an angle with the incident light.

  • Reflection and refraction are examined.

    The ray diagram of such a case can be seen as follows. (see attached file for diagram) 3) We have a relation between the refractive index and critical angle as u = 1/since(i_c).

  • Problems involving the refraction of light

    For a ray of light travelling from a denser to a rarer medium, there is an angle known as critical angle such that if the angle of incidence is greater than the critical angle, the ray suffers total internal reflection back into the denser medium.

  • Optics and Waves Question

    When this happens, total internal reflection occurs according to laws of reflection. Therefore, the reflected ray makes an angle of 55 degrees with the normal in water.
