Explain the basic behavior of waves, including travelling waves and standing waves
Waves are a common physical phenomenon that involves the transfer of energy from one place to another without any net displacement of the medium through which they travel. They can be categorized into two broad types: travelling waves and standing waves.
Describe the wave nature of light
Describe the wave nature of light
Light is an electromagnetic wave, which means it consists of oscillating electric and magnetic fields that propagate through space. The wave nature of light can be described by its wavelength, frequency, and speed.
The wavelength of light determines its color and is typically measured in nanometers (nm).
The frequency of light is directly proportional to its energy, and is measured in Hertz (Hz).
The speed of light in a vacuum is a constant, denoted by the symbol "c," which is approximately 299,792,458 meters per second (m/s).
Distinguish between line and continuous emission spectra
Distinguish between line and continuous emission spectra
Line and continuous emission spectra are two types of spectra that are produced when matter is excited (energized) and emits electromagnetic radiation.
Describe the particle nature of light
Describe the particle nature of light
The particle nature of light is a fundamental concept in physics that describes light as a stream of discrete, energy-containing particles called photons.
The particle nature of light was first proposed by Albert Einstein in 1905, when he used the idea of photons to explain the photoelectric effect, which is the emission of electrons from a metal surface when it is illuminated by light.
