What are two ways you can increase the strength of electromagnetic waves
1. Increase the amplitude of the waves: By increasing the amplitude of the waveform, you can increase the strength or intensity of the electromagnetic waves.
2. Increase the frequency of the waves: By increasing the frequency of the electromagnetic waves, you can also increase their strength. This is because higher frequency waves carry more energy per photon and therefore have a higher intensity.
True or false: electrostatic force is just like gravity, and that it is always an attractive force
False. While both electrostatic force and gravity are fundamental forces of nature, they operate in different ways.
Gravity is always an attractive force, meaning that it pulls objects towards each other. However, electrostatic force can be either attractive or repulsive, depending on the charge of the interacting objects. Like charges repel each other, while opposite charges attract each other.
