Reading Spectral Lines

What does a continuous spectrum display?

• Black lines on a colored background

• Only specific wavelengths of visible light

• All wavelengths of visible light from red to violet

• Only the red and violet wavelengths of visible light

How is a continuous spectrum produced?

• By reflecting light off a surface

• By absorbing certain wavelengths of light

• By emitting light at specific wavelengths

• Through dispersion of white light through a prism

What characterizes an absorption line spectrum?

• Only red and violet lines visible

• A continuous range of colors without interruption

• Colored lines on a black background

• Black lines on a colored background
