Imagine you shine a flashlight directly at a mirror, as shown below.
1. Draw an arrow showing the direction 2. Suppose you tilt the mirror. Draw an
you think the beam of light will most arrow showing the direction the beam
likely reflect off the mirror. will most likely reflect off the mirror now.
Gizmo Warm-up
Flashlights produce wide beams of light that
have various wavelengths. A laser, on the other
hand, is a narrow beam of light with only one
wavelength. All the waves in a laser beam are
parallel to one another. As a result, lasers are
ideal for studying reflection, or how waves
bounce off a surface.
Using the Laser Reflection Gizmo, you can
adjust the position of a laser beam and mirror to
study how light behaves when it is reflected.
1. Drag the Angle slider back and forth. Describe what happens to the reflected laser beam:
Sample answer: As the angle of the mirror changes, the angle of the reflected beam also
changes.
2. Drag the laser up and down. Describe what happens to the reflected laser beam:
Sample answer: The reflected beam moves up and down, but its angle does not change.
