In this applet, you can click on the wavelength/frequncy scale and change the wavelength and frequency by draggin the mouse around. You can also change the wavelength by using the arrow keys on your keyboard. Holding the shiftkey down while pressing the left or right arrow keys changes the wavelength by a factor of 10.

The violet and red "ends" of the optical spectrum are not really "ends" at all, but rather simply the limits to the portion of the EM spectrum to which our eyes are sensitive. Beyond red light lies the region known as the infrared, which is also simply known as heat radiation.
