Question
Which of the following forms a black shadow?
- Glass
- A frosted glass
- A brick wall
- Butter paper
Hint:
A brick wall is an opaque membrane that doesn't allow light to pass through it and shows a black shadow.
The correct answer is: A brick wall
- The object forms a black shadow when no light is passed through it.
- If the object allows light to pass through it, the shadow will be a little brighter depending on the amount of refracted light.
- An opaque object won't allow light to pass through it and shows a black shadow.
- The brick wall is an opaque membrane compared to the glass and frosted glass.

According to the second law of reflection, the angle of incidence is equal to the angle of reflection. Mark verified this fact by drawing the incident and the reflected rays. He also measured the angles made by the same incident and reflected rays with the reflecting surface (denoted as 1 and 2, respectively). Which of the following is true about the result that he might have got?
