On the way home from school, you stop at a stoplight. Suddenly you hear the siren of an ambulance in the distance. As you turn, you see the approaching vehicle so you wait patiently as the ambulance eventually speeds through the intersection. Describe the sound you hear throughout this process. Explain
your answer in terms of the Doppler Effect.

answerscientific theory;

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
