    WSL 12:

    a. Use at least two rays to construct the virtual image you see of yourself in a flat mirror. Remember it is upright and the same size as the object (you!)

    b. Construct the virtual image of an object seen through a double-concave lens. (Hint: it will be smaller and upright. Extra hint: double concave lenses have a virtual focal point!).


    WSL 13:

    a. What is the speed of sound if an echo takes 0.292 seconds to come back from a wall 5.0 meters away?


    WSL 14:

    a. Draw and calculate the frequency of a tone for which the first harmonic resonates in a tube (closed at one end) 45.0 cm long. (Assume 344 m/s speed)

    b. If a 1.50 meter long bass string creates a 50.0 Hz fundamental tone, what is the speed of the waves traveling through the string?
