Transparent plastic swimming-pool covers called solar heat sheets have thousands of small air-filled bubbles that resemble lenses.

The bubbles in these sheets are advertised to focus heat from the sun into the water, thereby raising its temperature.

Do you think these bublles direct more solar energy into the water? Defend your answer.

The bubbles will act as insulators being air filled - but focusing the light like a lens is not going to increase the toatl amount of energy entering the water - (they will only increase localised heating)
