A) Metal
B) Ceramic
C) Clear plastic sheet
D) Frosted glass.
Correct Answer: C
Solution :
Metal and ceramic are opaque materials, hence cast a shadow when light rays fall on them. Frosted glass is translucent hence it does not allow all light rays to pass through it hence, it also casts a light shadow. Transparent materials like clear plastic sheet allow all the light to pass through them and do not cast a shadow.You need to login to perform this action.
