To find:
The way aluminum/tin foil helps to cook the food faster in the solar oven.
Step-by-step explanation:
The solar oven is a device that utilizes solar energy from the sun to cook the food placed inside it. The energy from the solar radiation is trapped inside the oven and used to raise the temperature inside.
The aluminum/tin foil reflects a huge amount of solar radiation falling on it to the solar oven. This helps to increase the temperature inside the oven faster. Thus helping the oven to cook the food faster.
Final answer:
The aluminum/tin foil reflects the solar radiation to the inside of a solar oven, this helps to raise the inside temperature faster thus helping to cook the food faster.
