Speed of Sound in Air
Measure the speed of sound in air using a tube that is closed at one end. Use a Sound Sensor to record the initial pulse of sound and its echo. Calculate...
Superposition of Sound Waves
Two waves and their sum are created in the Capstone calculator and the effects of changing phases and amplitudes are examined in a graph.
Interference of Sound Waves
Measure and analyze the behavior of two sounds that combine to produce beats. Determine the relationship between the beat frequency and the frequencies...
Shadow and Color in Light
Use the Color Mixer to learn how three colors of light - red, blue, and green - add together to create a full range of colors. Examine how color filters...
Object and Image Distances Thin Lens
Determine the relationship between object distance and image distance for a thin convex lens. Use a light source, optics bench, lens, and viewing screen...
Reflection
Experimentally confirm the Law of Reflection for flat, concave, and convex mirrors.
Refraction
Use Snell’s Law of refraction to experimentally determine the index of refraction of a D-shaped acrylic lens.
Dispersion
Observe dispersion through an acrylic rhomboid and calculate the different indices or refraction for different colors of light.
Focal Length of a Concave Mirror
Use a light source, concave mirror, and half screen accessory on an optics bench to measure the focal length of the concave mirror.
Variation of Light Intensity
Compare the variation in intensity of light from different light sources. Use a light sensor to record and compare incandescent versus fluorescent light...
