The behavior of light rays reflecting off convex and concave mirrors through a series of questions and answers. Students will learn how to manipulate object positions and mirror focal lengths to measure image distance and size. Hypotheses about image size in relation to mirror types are also tested.

Objectives Observe light rays that reflect from a convex or concave mirror. Manipulate the position of an object and the focal length of the mirror and measure the distance and size of the resulting image. My hypothesis is that with a convex mirror the image will be smaller, but with concave mirror the image will be bigger. Data Q1: A light bulb is shown below, shining into a concave mirror, with its original light lines visible. Which statement best explains why the image of the bulb appears behind the mirror, as shown? A1: The reflected light appears to come from there. This is often indicated with dotted apparent light lines. Q2 An actual light bulb is shown below, with a concave mirror. The blue dot is the focal point of the mirror. What best describes the unseen image of this bulb? A2: Real, upside-down, and larger than the actual bulb.
Question 3: S=f^ 18s= S= Question 4: S96=120^ S96= 14400 S= Question 5 s^2=f^ s40,000=40, s= Summary To sum everything up the way the image reflects on the mirror and the distance. The image mirror and stance work with each other to determine how the image will be reflected. My hypothesis is accepted because when you use a convex mirror vs a concave mirror you get different images. With convex mirror the image is smaller.
