SUMMARY

The magnetic field amplitude of an electromagnetic wave can be calculated using the equation E₀ = B₀ * c, where E₀ is the electric field amplitude, B₀ is the magnetic field amplitude, and c is the speed of light (approximately 3 x 10^8 m/s). Given an electric field amplitude of 100 V/m, the correct calculation yields a magnetic field amplitude of approximately 3.33 x 10^-7 T (Tesla). The initial attempt of 0.0000003 T is incorrect due to a miscalculation in expressing the result as a decimal.

PREREQUISITES
  • Understanding of electromagnetic wave properties
  • Familiarity with the equation E₀ = B₀ * c
  • Basic knowledge of units in electromagnetism (V/m, T)
  • Ability to perform scientific notation calculations
NEXT STEPS
  • Learn how to derive the relationship between electric and magnetic fields in electromagnetic waves
  • Study the implications of electromagnetic wave properties in different media
  • Explore the concept of wave impedance in free space
  • Investigate applications of electromagnetic waves in communication technologies
USEFUL FOR

Students studying physics, particularly those focusing on electromagnetism, as well as educators looking for clear examples of electromagnetic wave calculations.

Homework Statement


What is the magnetic field amplitude of an electromagnetic wave whose electric field amplitude is 100V/m?



Homework Equations


Eo=Bo*c


The Attempt at a Solution



100/(3*10^8) = .0000003

Mastering physics says this is wrong though ^^

That looks fine to me. Now express this as a decimal.
