LIGHT 

EXPERIMENT 1

I'm going to light the laser pointer and point to the wall after you hobble a sprayer and pour water in the path of the pointer and you will see the beam of the pointer that traveled in a straight line.

 

EXPERIMEN 2 
I'm going to point to the wall and grab an ice cube and we'll see what happens to it bounces or reflects or bounces many times and the light appears in many places or turns red or goes through it. 


 in the video we have seen that the pointer has crossed the cube and at the same time

EXPERIMENT 3 

in the video I point to the glass the laser goes through the glass that also bounces on the tablet, you can also see that the light travels in a straight line.
