Answer: D) draw a conclusion

Explanation:

A conclusion in a scientific experiment is a descriptive content which includes the detail comparison of the data obtained from two or more separate variables by using the observations. It is the analytical and comparative part of an experimental study. It helps the experimenter to frame an inference on the basis of relating the conclusion with the chosen scientific principle or theory. This process will help in obtaining the result of the experiment.

On the basis of the above description, D) draw a conclusion is the correct option.

zloy xaker [14]

Answer:

1.5×10⁷ Hz

Explanation:

From the question given above, the following data were obtained:

Wavelength of radio wave (λ) = 20 m

Frequency (f) =?

Frequency and wavelength of a wave are related by the following equation:

v = λf

Where:

'v' is the velocity of electromagnetic wave.

'λ' is the wavelength

'f' is the frequency.

With the above formula, we can obtain the frequency of the radio wave as illustrated below:

Wavelength of radio wave (λ) = 20 m

Velocity (v) = 3×10⁸ m/s

Frequency (f) =?

v = λf

3×10⁸ = 20 × f

Divide both side by 20

f = 3×10⁸ / 20

f = 1.5×10⁷ Hz

Thus the frequency of the radio wave is 1.5×10⁷ Hz
