14. because violet light has more energy than red light,
a. red light is less bright than violet light.
b. violet light has a higher wave frequency than red light.
c. the mass properties of light are invariable.
d. violet light is preferable in a photographer's darkroom.

B. violet light has a higher wave frequency than red light.

Explanation:

The energy of a light wave is directly proportional to its frequency, according to the relationship:

where

E is the energy of the wave

h is the Planck constant

f is the frequency of the wave

The problem tells us that violet light has more energy than red light: since energy and frequency are directly proportional, this also means that violet light has higher frequency than red light, so the correct choice is

B. violet light has a higher wave frequency than red light.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
