Consider the following lighting parameters for a particular fragment: N is the normalized normal, L is the normalized vector to the light, V is the normalized vector to the camera, R is the normalized reflection vector, and a is the specular shininess. For each of the following Phong lighting components, calculate the component intensity using the above parameters and vector and$/$or trig functions listed in the exam instructions $($e$.$g$.,$ dot, sqrt$)$:

a$.(10)$ Specular:

b$.(10)$ Diffuse:
