Louisa put a bowl of water and a bowl of sand in the sun. she put a thermometer in each bowl. then she recorded the temperature at the start and after 30 minutes. after 30 minutes, the sand had heated more than the water. louisa’s experiment proved
a) sunlight does pass through water
b) sunlight heats liquids more than solids.
c) different materials heat up at different rates.
d) different materials absorb the same amount of heat.

the answer would be c

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
