Light & Geometric optics Quiz Review Notes

Things to know for your quiz: From scavenger hunt questions (Textbook) What is visible light? What is the visible spectrum? Need to be able to identify and label the visible and invisible regions of the electromagnetic spectrum. What are 3 types of luminous sources. How do they produce light? What is a light ray? How many light rays come from a candle? What is the difference between transparent, translucent, & opaque What is the meaning of image, object, and reflection?

Things to know for your quiz: From scavenger hunt questions (Textbook) What is specular and diffuse reflection? Give examples How do eyeglasses with color filters help people with dyslexia to read?

Properties of an image (salt) Be able to identify the properties of an image in plane and curved mirrors What does the acronym SALT stand for?

Ray Diagrams (Use textbook and day by day for studying) Need to show understanding, and be able to identify the of angle of incidence and angle of reflection on a ray diagram Need to show understanding, and be able to identify incident ray and reflected ray on a ray diagram Need to be able to create a ray diagram for a plane mirror and a curved mirror (and be able to draw/label all angles, rays).

The laws of reflection (Use textbook and day by day for studying) Need to show understanding and application of the laws of reflection for plane and curved mirrors Need to be able to complete a drawing that illustrates the laws of reflection for both plane and curved mirrors (using knowledge of angles of incidence and reflection)

Refraction (Use textbook and day by day for studying) Need to be able to demonstrate understanding of refraction Need to be able to explain how refraction works (i.e. what factors affect the refraction of light/how light bends as it passes from one medium to another) Need to be able to explain how different colors of light have different wavelengths, which influences the amount that they bend in a given medium

Refraction calculations (Use textbook and day by day for studying) Need to be able to calculate the index of refraction using the formula posted on the day by day (p. 524). Need to be able to calculate the speed of light in a given medium using the formula posted on the day by day (p. 524).

Total internal reflection (Use textbook and day by day for studying) What is the definition of total internal reflection? What is a critical angle? Need to be able to explain the conditions required for partial reflection/refraction and for total internal reflection.

Phenomena related to refraction (Use textbook and day by day for studying) How are rainbows formed? Why would they be considered a phenomena?
