Place the objects in order from least to most kinetic energy: •Pigeon flying 10 miles per

hour

•Train traveling 5 miles per

hour

•Person running 10 miles per

hour

•Bee flying 5 miles per hour

•Pigeon flying 5 miles per

hour

•Car driving 10 miles per hour

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
