Two students made the following statements to describe atmospheric conditions at a location.

Student X: The tropics are wet and warm.
Student Y: A hailstorm warning has been issued.

Which of these is true about the two statements?

A They both described climate.
B They both described weather.
C Student X described climate and Student Y described weather.
D Student X described weather and Student Y described climate.

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
