The frequency of waves is given in:
O
A. nodes per second
B. Waves per second.
O
C. graphs.
O
D. cycles per second.
SUBMI

B. Waves per second.

Explanation:

Wave frequency is the number of waves that pass a fixed point in a given amount of time. The SI unit for wave frequency is the hertz (Hz), where 1 hertz equals 1 wave passing a fixed point in 1 second. A higher-frequency wave has more energy than a lower-frequency wave with the same amplitude.

cad, or computer-aided design and drafting (cadd), is a software for design and technical documentation, which is an automated process as opposed to the manual drawing of plans. this gives a person an advance in making plans as an architect in a short period of time. one who can render plans through this software will gain a skill that is better than one who makes plans manually. this is a skill some companies look for in an employee.
