1 Fig. 1.1 shows a spring hanging from a wooden rod with a load attached to the lower end of
the spring

(a) On Fig. 1.1, mark
(i) the length 1 of the spring,
[1]
(ii) the position of the ruler used to measure the length I
(iii) where you would position your eye to determine the reading for the bottom of the
spring
[1]

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
