1. If light traveling along an obstructed path has varying frequencies. What frequencies tend to survive more despite the obstructions to lit a surface. You should present your answer as discussion stating reasons behind your answer 2. The R.G.B colour at I. = (0.55, 0.34, 0.12) and R.G.B colour at I, = (0.2, 0.45, 0.1). Compute the R.G.B of the interior pixel, I, of the below given triangle using the Gouraud smooth shading equation. Note that this is a process the linear interpolation also follows, nn n n MM MM a. Above question b. What advantage does Gouraud shading have over flat shading? 3. Answer the questions below. a. What color will you observe as the color reflected off a red car lit by the sun light? Make sure to make reference to the properties of light when explaining. b. State why a sphere will appear black under blue light. 4. Using an example, explain what you understand by push and pop matrix and why you would use them 5. State when perspective projection can be used over orthographic projection. 6. Describe the factors that determine the intensity of light at a point on a surface
