Why do microwave ovens heat food but tend not to heat the dish the food is on?
You left a glass full of homogenized milk on a table undisturbed for half an hour.
What would result if you shined a laser beam against the side of the glass? *
The beam of light will be reflected back to its original source.
No light will pass through the two side of the glass.
A path of light will be visible from one side of the glass.
The beam of light will not be reflected nor will it be visible.
