Dive into the world of equations along with JEE Main Electromagnetic Waves Important Questions and amplify your study sessions. Explore our Physics formula pages to start your preparation journey for JEE Main today!


Important Formulas of Electromagnetic Waves

1. Maxwell's Equations

$\begin{aligned}& \oint E \cdot d A=Q / \varepsilon_0 \\& \oint B \cdot d A=0 \\& \oint E \cdot d \iota=\frac{-d \phi B}{d t} \\& \oint B \cdot d l=\mu_0 i_c+\mu_0 \epsilon_0 \frac{d \phi_E}{d t}\end{aligned}$

(Gauss's Law for electricity)

(Gauss's Law for magnetism)

(Faraday's Law)

(Ampere-Maxwell Law)


2. Oscillating Electric and Magnetic Fields

$\begin{aligned}& E=E_x(t)=E_0 \sin (K Z-\varpi t) \\& =E_0 \sin \left[2 \pi\left(\frac{z}{\lambda}-v t\right)\right]=E_0 \sin \left[2 \pi\left(\frac{z}{\lambda}-\frac{t}{T}\right)\right] \quad E_0 / B_0=c\end{aligned}$

$c=1 \sqrt{\mu_0 \epsilon_0} \quad$, c is speed of light in vaccum

$v=1 / \sqrt{\mu \epsilon} \quad, \mathrm{v}$ is speed of light in medium

$p=\frac{U}{c}$, energy transferred to a surface in time $\mathrm{t}$ is $\mathrm{U}$, the magnitude of the total momentum delivered to this surface (for complete absorption) is $\mathrm{p}$
