A shipping pallet holds 10 boxes. Each box holds 300 parts of differenttypes. The part weight is normally distributed with a mean of 1 lb and astandard deviation of 0.2 lb. a. Compute the mean and standard deviation of the pallet weight. b. Compute the probability that the pallet weight will exceed 3015 lb.

does anyone know or what?

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
