what will happen if light passes through changing magnetic field?
Assuming it's in a vacuum, i.e. a charge-free space, it keeps on going straight with no change in frequency.spidey said:what will happen if light passes through changing magnetic field?

spidey said:what i meant,will there be any change in the frequency or energy of light after passing through changing magnetic field

That's interesting. I always thought that the two different waves mix with each other to form one with a different frequency.atyy said:So why is the sum of two waves a different visual colour? Well, each wave itself stimulates a particular colour receptor in your retina. Different combinations of waves stimulate different combinations of colour receptors, and what colour you see is really a biological question (and there are interesting effects where light of the same wavelength appears a different colour depending on the colour of its surroundings):http://www.designmatrix.com/pl/cyberpl/cic.html.

Light and a changing magnetic field are closely related through the phenomenon of electromagnetic induction. When a magnetic field changes, it creates an electric field, which can in turn create a changing magnetic field. This changing magnetic field can then produce electromagnetic waves, or light.
In a changing magnetic field, light exhibits the properties of both a wave and a particle. It behaves as a wave as it travels through the magnetic field, but also as a particle when it is absorbed or emitted by matter.
A changing magnetic field can affect the speed of light by causing it to deviate from its usual path. This is known as the Faraday effect and is used in devices such as optical isolators and modulators.
Yes, a changing magnetic field can produce visible light. This is known as electromagnetic induction and is the basis for the creation of light in devices such as generators and motors.
Light in changing magnetic fields has a wide range of practical applications, including communication technologies such as radios and televisions, medical imaging techniques such as MRI machines, and energy production through solar panels.
