Detailed Solution

Assertion is true, but Reason is false.
Assertion: We know that a solar cooker is a cooking device that cooks food without electricity consumption. Food is placed on a tray and topped with a glass cover in a solar cooker. It has a mirror that reflects the sun's rays onto the food. This process warms up the food, and the glass lid stops this heat from escaping. The heat from the sun cooks the meal. A plane mirror provides uniform reflection and heating of the overall food tray, whereas a parabolic concave mirror focuses more of the sun's rays onto a small region.
Reason: A solar cooker cannot be used to cook food on cloudy days and during the night as it requires solar energy, which is the energy obtained from the sun to cook food, and this energy is not available during cloudy days and at night.
