White light can be split up to form a spectrumclosespectrumRefers to the visible spectrum, the range of the electromagnetic spectrum visible to the human eye. It can be seen when white light is split by a prism, or by raindrops to form a rainbow. using a prismcloseprismA block of glass or other transparent material that disperses light to form a spectrum..

Refraction byprism

Optional. A grating with 12,000 lines per centimeter is used with light of wavelength 650nm. What is the angle of the first bright spot? __________

Opticaprism

Optional. Suppose double slits are spaced 1.33×10?4 m apart and light of 500nm wavelength shines through them. What distance from the center spot will the second bright spot appear on a screen 4m away? __________

Optional. What effect on the double slit pattern will result from an increase in the wavelength of light? ____________________

Light waves are refractedcloserefractionProcess by which a wave changes speed and sometimes direction upon entering a denser or less dense medium, eg a light ray changes direction when refracted by a lens. as they enter the glass because they are slowed down.
