Light
is a type of energy we can see

Light travels
in straight lines called rays

short wavelength
more energy
Vacuum
light can travel through vacuums
nothing is found faster then light
true
if light enters a transparent material at an angle, it both slows down and changes direction. This sudden change in a light beam is called refraction
true
Light does not travel in a straight line
false
