500
What causes sound waves?
vibrations
500

Why does refraction occur?

because light travels from one density to another

500
What is the difference between digital and analog signaling?

analog signals are continuous and can take on any value within a range, while digital signals are discrete, meaning they only represent information in specific, fixed values, usually represented as binary digits (0s and 1s) making them less susceptible to noise and interference compared to analog signals.
