Refraction of Microscopic Lasers to Find Abnormalities in Cancer Cells
... Reflection: Light is reflected when it bounces off a certain medium and returns in a direction towards the light source. A similar experiment to the diffraction occurred where we tested the spacing between the microscopic grooves on a CD. We shined a laser at a CD and we were able to see the light b ...
