Answer 2

Frosted glass is not opaque. (option b)

• Opaque materials are those which donot allow refraction of light and are hence not transparent.
• Common examples are iron, wood and cardboard which are solids which donot allow us to see through them.
• Frosted glass is an example of a translucent material. Such materials allow light to only partially refract and are hence semi-transparent.
