Three cuboids made of glass, iron and lead with the same base area and the same mass are heated to the same temperature and then placed on a thick, cold wax plate. Which cuboid sinks the deepest when the wax melts? (Justify

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.

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
