Question

Which is the largest wavelength?

O A. 7.7 x 104 m
OB. 9.7 x 102 m
00
O C. 1.4 x 105 m
OD. 8.3 x 10³ m

Answer 1

The largest wavelength among the given options is option C:
`\(1.4 * 10^5\)` meters.

Wavelength is a measure of the distance between successive peaks (or troughs) of a wave. The wavelength of a wave is inversely proportional to its frequency, and it is commonly expressed in meters.

In the provided options:

- Option A has a wavelength of
`\(7.7 * 10^4\)` meters.

- Option B has a wavelength of
`\(9.7 * 10^2\)` meters.

- Option C has the largest wavelength,
`\(1.4 * 10^5\)` meters.

- Option D has a wavelength of
`\(8.3 * 10^3\)` meters.

Comparing the values, option C has the largest numerical value for wavelength, making it the correct answer for the largest wavelength among the given choices.
