A student measures the frequency of a wave as 2 waves/second, and the wavelength as 40 cm/wave. Use the velocity equation (v = f × λ) to calculate the speed of the wave. Show your work and include units.

This flow chart shows the amount of energy that is emitted by each type of light. ultraviolet > blue light > yellow light > red light (maximum energy) (minimum energy) in an experiment, shining which type of light on a strip of metal would be least likely to produce the photoelectric effect? ultraviolet light dim blue light bright red light bright yellow light
