Two objects, A and B, have the same size and shape and mass. Object A lands on a foam cushion while object B lands on concrete. Both objects will have the same impulse, but object A will have a
collision time and a
force of impact.

A. Smaller: smaller
B. Bigger; smaller
C. Bigger; bigger
D. Smaller; bigger

reserve is the answer

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
