Absorption and Emission (7.1.2)

Question 1

• The color of light depends on the wavelengths of which it is composed and the observed color of an object is due to the wavelengths that were not absorbed by the object.

Answer 1

• The color of light depends on the wavelengths of which it is composed and the observed color of an object is due to the wavelengths that were not absorbed by the object.

Question 2

• An absorption spectrum is a plot of the intensity of light absorbed by a sample versus wavelength.

Answer 2

• An absorption spectrum is a plot of the intensity of light absorbed by a sample versus wavelength.

Question 3

• An emission spectrum is a plot of the intensity of light emitted by a source versus wavelength.

Answer 3

• An emission spectrum is a plot of the intensity of light emitted by a source versus wavelength.
