Winds move in a direction in the northern hemisphere and in a direction in the southern hemisphere because of the coriolis effect.

To firstly answer this question, you must know what the Coriolis effect is. In simple terms, it can be defined as something that causes displacement - making things move at a curve, rather than a straight line. This aforementioned effect applies to winds within the hemispheres. Here's how this effect messes with the winds.

Winds move in a counterclockwise direction in the Northern Hemisphere and in a clockwise direction in the S. Hemisphere.

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
