What is light?
—Light is electromagnetic radiation that enables us to see. It has both wave and particle properties.
How does light travel?
—Light travels at a constant speed in a wave-like motion. It does not require a medium to propagate, unlike other types of waves.
Can light be absorbed or reflected?
—Yes, light can be absorbed by objects, causing them to heat up, or reflected, allowing us to see them.
What determines the properties of light?
—The wavelength and frequency of light determine its properties, such as color and energy.
Why is understanding light important?
—Understanding the nature of light is crucial for various fields, including optics, telecommunications, and astronomy.
