Why are reflectors used in a solar cooker?

  1. To absorb infrared rays
  2. To focus sunlight onto the cooker
  3. To cool the cooker
  4. To prevent dust accumulation
Show answer and solution

Correct answer: B. To focus sunlight onto the cooker

1. The cooker receives more solar energy than the direct overhead beam alone. 2. Reflectors are mirrors mounted around the cooker. 3. They catch sunlight from angles and reflect it onto the cooker. 4. The cooker therefore receives a more intense beam. 5. So reflectors concentrate sunlight onto the cooker. _Source: syllabus Science Ch 14 'Sources of Energy' (byjus.com extract)_
