Answer please
what kind of energy does a bent ruler have
light can only be bent when driven into a large star with nuclear power- or something like that
total internal refraction
That is not strictly correct. The straw has undergone physical change: it is wet!
bent sound waves
what kind of energy does a bent ruler have
It's when a material gets bent, squashed or otherwise changes shape to the point where it can't change back when the load is removed.
larger underwater
nah owens sound hes about as bent as a ruler.
If you heat a type of plastic and bend it and let it cool down bent it will stay bent, but if you hold the bent plastic on or over the heat it will bend back so it's straight again
She bent down, turned around, and gave me a wink- and then it happened.
The material must be flexible - it must change its shape. Plasticene (modelling clay) or a soft plastic rod would be examples. It need not be soft however, a metal spring or strip would be bendable.
That is related to the speed of the electromagnetic wave in the material.
yes it is true
It depends on the precise material and the dimensions of the rod
It can be bent, and it conducts electricity.
