- Identify the portion of the eye responsible for most of the focusing of light.
- What is the purpose of the iris?
- In geometric optics, we do analyses using similar triangles. This problem is here to help you practice working on these again.
- Look at this map and determine the angle.
- For this set of intersecting lines, use the following information to find the missing values.
- Indicate where the outgoing ray from a mirror intersects the dotted line.
- When given the indices of refraction for water, calculate the speed of light in water and in glycerine.
- Calculate the index of refraction for a medium when given the speed of light.
- Consider two materials. When light passes through the space between the two materials at 0°<θ<90°, there is no change in the direction of the propagation of the light. What can you infer about the two materials?
- Which of the properties of a light ray change as it goes from glass to vacuum?
- What are the wavelengths of visible light in crown glass?
- Calculate the index of refraction for an unknown clear substance in water.
- A beam of white light goes from air into water at an incident angle. Calculate the angles at which red and violet parts of the light are refracted when the indices of refraction are given.
- Find the height of the instructor’s head above the water when the angle between the ray in the water and the perpendicular to the water is known.
- Sign conventions for object and image distances: objects and images on opposite sides of the optical element.
- Sign conventions for object and image distances: objects and images on same side of the optical element.
