Waves Introduction

A wave is a disturbance that travels through a medium from one point to another. SO they are created a wiggle or vibration in a medium. Wave theory is the idea that waves consist of disturbances which transfer energy. This is important because it allows us to understand what waves do through daily tasks. Wave theory is used in light, oceans, and even sound. Which are things that are around us everyday.


Transverse: A wave in which the direction of displacement is perpendicular to the direction of propagation

- Transverse waves are important to everyday life for various of reasons. Some of those being moving the ocean water and other real life example is a crowd at a game doing the wave in the stands.

Longitudinal: A wave in which the direction of the wave and its propagation are parallel to each other

- Real life examples of longitudinal waves would be splinkys, and even sound waves carry the form of longitudinal waves sometimes.

Simple Waves

Spherical Waves and Plane waves

Spherical waves are emitted from a single point in a spherical shape


A plane wave constant-frequency wave whose wavefronts parallel planes

Interference

Dual Pin and Double Slit Interference

Dual Pin: interference from two sets of concentric waves that share the same frequency

Double Slit: Interference from two sets of waves that was originally one wave but traveled through a barrier with two slits.


Constructive Interference: Combination of two or more waves that results in a new wave pattern with a greater amplitude

Destructive Interference: two or more waves that are in different phases that combine with each other cancelling resulting in waves of smaller amplitude

Reflection

Wave Reflection

Change in the waves direction after bouncing off a barrier


Law of Reflection: States that the angle of reflection is equal to the angle of incidence

Reflection

Diffraction

Change in the intensity or direction of a wave after passing through and obstruction. small diffraction; great deflection
