\higher frequency light carries more energy in each packet.\
read the quote. what is the meaning of frequency as it is used in this context?
a the intensity of loudness or sound
b the push or pull force an object exerts
c the rate at which something occurs over a period of time
d the weight of an object in relation to its height

Explanation:

To determine the meaning of "frequency" in the context of light energy, we analyze each option:

• Option A refers to sound intensity, which is irrelevant to light.
• Option B describes force, not related to frequency.
• Option C defines frequency as the rate of occurrence over time, which matches the scientific concept of light frequency (how often light waves oscillate per unit time).
• Option D relates to weight/height, unrelated to frequency.

Answer:

C. the rate at which something occurs over a period of time
