List 2 ways that u can increase the strength of electromagnetic waves. Explain how each method will effectively increase the strength
1. Increase the power of the source: One way to increase the strength of electromagnetic waves is to increase the power output of the source generating the waves. Electromagnetic waves are produced by oscillating electric and magnetic fields, and the power of the source determines the intensity of these fields. By increasing the power output of the source, the amplitude of the electric and magnetic fields will also increase, resulting in stronger electromagnetic waves being emitted.
2. Increase the number of oscillations: Another way to increase the strength of electromagnetic waves is to increase the frequency of oscillation of the source. Electromagnetic waves are composed of oscillating electric and magnetic fields, and the frequency of these oscillations determines the wavelength and energy of the waves. By increasing the frequency of oscillation, the wave will have more oscillations per unit time, resulting in a higher energy level and stronger electromagnetic waves being emitted.
