The wavelength of a radio wave whose frequency is 900 kHz will be 10³/3, or you can write it as 333.33 meters.
To characterize waveform signals that are transmitted across wires or into space, the term "wavelength" is used to refer to the separation between two identical positions (adjacent crests) in succeeding cycles. Typically, this length in wireless systems is measured in meters (m), centimeters (cm), or millimeters (mm) (mm). When describing the wavelength of infrared (IR), visible light (UV), and gamma radiation, units of 10⁻⁹ nanometers (nm) or angstroms (10-10 m) are more usually used.
Frequency, which is defined as the number of wave cycles per second, and wavelength have an inverse relationship. The wavelength of a signal decreases with increasing frequency, or we can say that wavelength and refractive index are inversely proportional to each other.
According to the question, the given values are :
v = 3 × 10⁸ m/s and,
frequency, f = 900 kHz or,
f = 900 × 10³ Hz
λ = v / f
λ = (3 × 10⁸) / (3 × 10³)
λ = 10³/3 metes or,
λ = 333.33 meters.
So, the wavelength of a radio wave is 333.33 meters.

Explanation:
To determine which force does more work, we can calculate the work done by each force using the formula:
Work = Force × Distance
For the first scenario:
Work = 500 N × 10 m = 5000 N·m
For the second scenario:
Work = 100 N × 40 m = 4000 N·m
Therefore, the force of 500 N moving through 10 m does more work, with a total of 5000 N·m.
