LIght Color Electromagnetic Wave Test

Red has the ________ wavelength. Violet has the ________ wavelength

• longest; shortest

• shortest; longest

How do we see color?

• When light hits an object some wavelengths are reflected and others are absorbed. We see the color being reflected back to our eyes.

• When light hits an object some colors are absorbed and others are reflected. We see the color being absorbed back to our eyes.

• When light hits an object some wavelengths are refracted and others are transmitted. We see the color being refracted back to our eyes.

• When light hits an object some frequencies are dissolved and others are reflected. We see the color being dissolved back to our eyes.
