The rider rings a bell on their bike and emits a 710 Hz sound. 14. Does the jogger hear a higher, lower, or the same pitch (highlight one)? Higher Lower Same 15. What is the wavelength of the sound wave? Given(s) Unknown(s) Equation(s) Substitution(s) Solution Mars is about 2.25 x 10" meters away from earth. 16. How long would it take an electromagnetic radio wave sent from a rover on Mars to reach earth? Given(s) Unknown(s) Equation(s) Substitution(s) Solution A plant is green because it absorbs all color wavelengths except green, which has a wavelength of 500 nm. 17. Calculate the frequency of green light. Given(s) Unknown(s) Equation(s) Substitution(s) Solution
