Save guides, add subjects and pick up where you left off with your BBC account. Brush up on your refraction of light knowledge and understanding with our National 5 Physics revision article.

Recent experiments that demonstrate the negative refraction of light could bring a heated scientific debate to a close, and give negative-index materials a positive future Figure 1: Negative-index ...

Scientists have created a new class of laser beam that appears to violate long-held laws of light physics. These new beams, which the team calls “spacetime wave packets,” follow different rules of ...

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 ...

"The colors of the spectrum, then, "are not Qualifications [alterations] of Light … (as 'tis generally believed), but Original and connate properties." When you purchase through links on our site, we ...
