Question:
What is the role of a plane mirror and a glass sheet in a solar cooker ?
Solution:
A solar cooker covered by a plane glass slab will be more efficient.
This is because glass slab does not allow the heat radiation to escape from the solar cooker and hence the temperature of the solar cooker covered
with glass slab increases more than the temperature of the solar cooker which is left open.
