What color is the coronavirus? Conventional optical microscopes are unable to generate high-resolution, colored images of viruses and bacteria. Expensive equipment is used to view them in a more real ...

The incident angle can be varied from 0 to 85 degrees. (In 5 degree increments using the +-5 buttons.) The index of refraction of the first medium is fixed at n=1.00. The index of refraction of the ...

Light refracts and reflects when it reaches a medium with a different index of refraction. The index of refraction of mineral oil is almost identical to that of a glass tube, so light does not refract ...
