How Do Rainbows Form?
In this video, you will learn how rainbows are formed through the behavior of light waves. Sunlight, composed of different wavelengths, enters raindrops, causing the light to split into a multitude of colors. As the light refracts and...

NASA | First Sightings of How a CME Forms
On July 18, 2012, a fairly small explosion of light burst off the lower right limb of the sun. Such flares often come with an associated eruption of solar material, known as a coronal mass ejection or CME -- but this one did not....

What is the period, frequency and amplitude of sine and cosine graphs
👉 Learn the basics to graphing sine and cosine functions. The sine graph is a sinusiodal graph with x-intercepts at x = 2n*pi, maximun value of 1 at x = pi/2 + 2n*pi and minimum value of -1 at x = -pi/2 + 2n*pi. The cosine graph is a...
