Question

Define the terms and state their SI unit (1) time (2) Frequency (3) wavelength .​

Answer 1

Answer:

time: an event or an occasion that you experience in some other way .

SI unit:seconds

frequency:no. of oscillations in a second

SI unit:hz

wavelength: the distance between two sound waves

SI unit:meters

Answer 2

Answer:

Time period is defined as a vibrating particle to complete one vibration oscillation. It is denoted by T. It's S.I unit is second.

OR

time. "The second, symbol s, is the SI unit of time. It is defined by taking the fixed numerical value of the caesium frequency ∆νCs, the unperturbed ground-state hyperfine transition frequency of the caesium 133 atom, to be 9192631770 when expressed in the unit Hz, which is equal to s−1."

Wavelength : It is defined as the distance travelled by a wave during the time a particle of the medium completes one vibration. It is denoted by k. Its SI unit is metre.

Frequency: It is the number of occurrences of a repeating event per unit of time. Its SI unit is Hertz (Hz).
