The solar cooker contains glass. The glass allows the rays of light having a higher wavelength to enter the solar cooker. But during the exit of the ray of the light having low wavelength is prevent.  

Explanation:

  • The low wavelength of light is trapped there. Hence the heat does not move outside.  
  • Also as glass is poor conductors of heat, heat does not move out of the solar cooker.
  • Hence the solar cooker remains hot. Thus the food can be cooked with lower energy.
