Why may the value of an object behind transparent glass appear darker or lighter in some areas?

Answer and explanation

Correct answer: Because of reflection, refraction, and glass thickness

The governing concept is transparent-surface observation. Glass transmits light but also reflects surroundings and refracts rays as they pass through its surfaces; variations in thickness, curvature, or viewing angle can therefore shift the observed value of the object behind it. Option A is correct. Glass does not always change colour, and neither a pencil nor the paper can physically erase or supply different light to the hidden object.
