একটি সমতল ইলেক্ট্রোম্যাগনেটিক ওয়েভের চৌম্বক ক্ষেত্রটি `B_(y) = 2xx10^7 T sin (0.5xx10^3...) দ্বারা দেওয়া হয়।

0.5xx10^(-4)xx0.3xx10^(-3)xx10

Simplify: 2^3xx5 (ii) 0xx10^2

3 xx 10^(5) + 4 xx 10^(3) + 7 xx 10^(2) + 5 is equal to

The magnetic field in a plane electromagnetic wave is given by B_(y) = 2xx10^7 T sin (0.5xx10^3x+1.5xx10^11 t) T (a) What is the wavelength and frequency of the wave? (b) Write an expression for the eletric field.

3xx10^(5) + 4xx10^(3) + 7xx10^(2) + 5 is equal to

{5/7 xx (1/2)} + { 5/7 xx (-5/10)}

The magnetic field in a plane electromagnetic wave is given by B_(y) = 2 xx 10^(-7) sin (0.5 xx 10^(3)x + 1.5 xx 10^(11) t) . This electromagnetic wave is

For a plane electromagnetic wave, the magnetic field at a point x and time t is vec(B) (x,t) = [1.2 xx 10^(-7) sin (0.5 xx 10^3x + 1.5 xx 10^11t)hatk]T The instantaneous electric field vecE corresponding to vecB is : (spped of light c = 3 xx 10^8 ms^(-1) )

The magnetic field in a plane electromagnetic wave is: B_y = 2 xx 10^(-7) sin ( 0.5 xx 10^8 x + 1.5 xx 10^(11) t) T. What is the wavelength and frequency of the wave?
