Answer:
Wavelength of electromagnetic wave = 4.0 × 10³
Explanation:
Given:
Wavelength of electromagnetic wave = 4000 meter
Find:
Write, Wavelength of electromagnetic wave into scientific notation
Computation:
Wavelength of electromagnetic wave = 4000 meter
Wavelength of electromagnetic wave = 4.0 × 1,000 meter
Wavelength of electromagnetic wave = 4.0 × 10³
So,
Option "B" is the correct answer to the following question.
