Exploring wave speed in physics, this overview covers how waves travel through different mediums and the factors affecting their velocity. It delves into the calculation of wave speed using frequency and wavelength, the impact of the medium's properties, and the variations in speed due to environmental conditions. The text also examines the unique behavior of electromagnetic waves, including the constant speed of light and how material density influences it.

Wave speed is calculated by multiplying the frequency of a wave by its wavelength
Physical Properties of the Medium
The speed of a wave is influenced by the density, elasticity, and temperature of the medium it travels through
Type of Wave
Different types of waves, such as mechanical and electromagnetic waves, interact with mediums in different ways
Wave speed can be determined using the wave's frequency, wavelength, or period
The speed of sound in a medium is influenced by its density and temperature
Deep Water Waves
In deep water, the speed of a wave is determined by its period and the acceleration due to gravity
Shallow Water Waves
In shallow water, the speed of a wave is dependent on the water depth
Electromagnetic waves, such as light, can travel through a vacuum at a constant speed, but their speed is reduced when passing through different materials
The refractive index is a measure of how much the speed of light is reduced when passing through a material
The denser the material, the more the speed of light is reduced when passing through it, resulting in a higher refractive index
