The phenomenon where different colors of light separate due to dispersion is called:

For a concave mirror, the focal length is:

The mirror formula is \( \frac{1}{f} = \frac{1}{p} + \frac{1}{q} \). The quantity \( q \) is positive if the image is:

The lensmaker's formula is \( \frac{1}{f} = (\mu - 1)(\frac{1}{R_1} - \frac{1}{R_2}) \). For a plano-convex lens, \( R_2 \) is:

The power of a lens is measured in:

For a converging lens, the focal length is:

In the lens formula, a virtual image has a:

The magnification of a lens is given by \( M = -\frac{q}{p} \). A negative magnification indicates that the image is:
