6.6 * V/m is the electric field amplitude of an electromagnetic wave whose magnetic field amplitude is 2.20 mT
<h3>Given the data in the question:</h3>
Magnetic field amplitude = Bm = 2.20 mT = 2* T
Electric field amplitude = Em = ?
<h3>Electric field:</h3>
An electric field is a field created by electrically charged particles that attracts or repels other electrically charged particles surrounding it.
The greatest strength of the electric and magnetic fields is known as the electric field amplitude.
It can be said to be,
Em = c * Bm
Where, c is the speed of light(c = 3 * m/s)
Bm is the magnetic field amplitude
On substituting the values we get,
Em = c * Bm
Em = 3 * m/s * 2.20 * T
Em = 660000 V/m
Em = 6.6 * V/m

Infrared rays are used in many forms of thermal technology. This is also used in weather reports to find the temperature of the surrounding areas.
29 million are type 2, that would be about 9.5 percent. :)
Answer:
Explanation:
The relationship between angular acceleration α and torque τ is given by :
Here,
is the moment of inertia. It depends on the mass and the distance from the axis of rotation.
is the angular acceleration
Hence, this is the required solution.
Answer:
6.97 E 16
Explanation:
Frequency is a function of velocity of light to it's wavelength.
Mathematically written as
F = Velocity / wavelength
Velocity of light = 3 x 10^8
Wavelength =430 nm =430 x 10^-9 m
converting wavelength from nanaometer to meter we divide by 10^9
Frequency = (3 x 10^8)/(430 x10^-9) =6.97 E 16
