Answer:
588m
Explanation:
frequency = 510 kHz
speed of all electromagnetic waves are 3×10⁸ in any medium
speed = frequency × wavelength
wavelength = speed ÷ frequency
= 3×10⁸ ÷ 510 × 10³ =588.2352941 ≈ 588 m(3s.f.)
since there is a prefix of kilo in the frequency value, then we have to include the calculation of the prefix in order to find the wavelength as all calculated values should be in SI unit
