An electromagnetic wave in a vacuum traveling in the +x direction generated by a variable source initially has a wavelength λ of 255 μm and a maximum electric field Emax in the +y direction of 2.20×10−3 V/m . The period of the wave is then increased by a factor of 1.70. What are the coefficients in the equation for the magnetic field component of the wave after the period increases by a factor of 1.70? Enter the maximum magnetic field, wavenumber, and angular frequency in teslas, inverse meters, and radians per second separated by commas. (Bmax, k,ω)

compass can be used day and night, cloudy or sunny

1.   what is light?

light is an electromagnetic wave visible to the human eye. 

2. what is a reflection?

the rebounding of a light ray when it hits a mirror.

3. what is the incident ray?

contacts the surface of an object.

4. what is the reflected ray?

bounces off a reflective surface.

5. what is the normal ray?

perpendicular to the surface of a mirror.

6. what is the angle of incidence?

an angle formed by the incident ray and the normal.

7. what is the angle of reflection?

an angle formed by the reflected ray and the normal.

8. what is refraction?

(bending.)

9. what is a converging lens?

bring together light rays that pass through.

10. what is a diverging lens?

spreads out light passing through.

11. focal point?

the real point where the refracted rays meet when the incident rays run parallel.
