The complete pattern of a pendulum is ...
-- out to one side
-- back to the center
-- out to the OTHER side
-- back to the center.
So, on the graph, the complete period is one up-loop and one down-loop.
That's <em>6 seconds</em>. (b)
27).
This question is just asking for the frequency, without using the word.
Frequency is always (1/period). That's <em>1/6 of a second</em>. (a)
(This kinda makes sense. If you want to do something in 6 seconds, you need to do 1/6 of it every second. Right ?)
Answer:
Frequency
Explanation:
The intensity of light is increased by increasing the number of photon per second, and the number of photon per second is referred to as frequency. A photon the smallest unit of light. If the frequency is increased, the number of photons per second increases hence an increase in intensity.

Temperature is defined by the agitation of molecules on a molecular level. it is OK when all of the particles are still, but increases when the agitation becomes more intense.
