How do the properties of an electromagnetic wave change as a result of increasing the period of the wave?

a .increase
b. stay the same
c. decreasing

Explanation:

All matter contains charged particles that are always moving therefore, all objects emit EM waves.

The relation between the magnetic field and electric field is

B_{max}= c E_{max}

The wavelength becomes shorter as the temperature of the material increases.

As frequency increases, wavelength becomes smaller.

Frequency is inversely proportional to the period of time so, when increasing the period of wave, frequency decreases, wavelength becomes larger.

wave number is inversely proportional to wave length.

so, increasing wavelength decrease the wave number.

1. wavelength increases.

2. B_max  remains the same

3. polarization is same

4. wave number decreases

5. frequency decreases

6. E_max is also same

7. angular frequency decreases.
