Waves

Arbor Scientific is providing physics and physical science teachers with a collection of student lab activities for the study of Waves. Here you can browse lab activities by title and get teachers notes, student worksheets and a list of equipment and supplies needed for each activity.

  • Tuning Fork Interference

    Posted on January 1, 2011 by Arbor Scientific

    Tuning Fork Interference
    Two waves, when traveling through the same medium, will superimpose upon one another, causing interference. In the case of sound, the two sounds will combine to form a single sound. This lab asks students to combine the sounds from two tuning forks (which each produces a simple sine wave vibration) and observe the [...]

  • Slinky waves

    Posted on January 1, 2011 by Buzz Putnam

    Students investigate properties of mechanical waves using a "slinky" spring: wavelength, speed, reflection, standing waves, interference.

    Good for grade levels 5 through 8

    Required Equipment
    Super Springy, Stopwatch, String, Masking Tape, Helical Spring

    Acknowledgements: Thank you to Dwight "Buzz" Putnam for his assistance in developing this lab. Buzz is a 25 year veteran physics teacher at Whitesboro High School, New [...]

  • Refraction and Total Internal Reflection

    Posted on January 1, 2011 by Arbor Scientific

    Refraction and Total Internal ReflectionStudents will be able to observe that refraction (bending) always takes place at the interface between two different transparent materials and that the angle of refraction in plastic is smaller than the angle of incidence in air. The light is directed at the center of the semicircular cup where it is [...]

  • Waves on a Helical Spring

    Posted on January 1, 2011 by Arbor Scientific

    Waves on a Helical Spring
    Students investigate properties of mechanical waves using a helical spring: wavelength, speed, reflection, standing waves, interference. Neither amplitude nor frequency affects wave speed. As wave frequency goes up, wavelength goes down, and vice versa. Wave pulses can interfere constructively (adding together when on the same side of the spring) or destructively.

  • Wave Motion

    Posted on January 1, 2011 by David Burch

    It's the “wow” when kids realize the demo isn't just entertainment...“We can't drill to the center of the Earth, so how do we know about its crust, mantle, inner and outer core? How can we find the epicenter of an earthquake? I demonstrate how we make inferences as sound waves interact with boundaries. Students see [...]
