    Study Notes

    Wave Characteristics

    • Wavelength is the distance between consecutive points on a wave that are in phase with each other.

    Types of Waves

    • Electromagnetic waves can travel through both matter and space.
    • Sound belongs to mechanical waves.

    Mechanical Waves vs Electromagnetic Waves

    • Mechanical waves require a medium to propagate, whereas electromagnetic waves do not.

    Light Interactions

    • Absorption of light occurs when light is taken in by a material, converting it to other forms of energy.
    • Reflection of light is the change in direction of light when it hits a surface, bouncing back without being absorbed.
    • Refraction of light refers to the bending of light as it passes from one medium to another with a different optical density.

    Visible Light

    • The relative strength/frequency order of colors in visible light is: Red, Orange, Yellow, Green, Blue, Indigo, Violet (ROYGBIV).

    Material Interactions

    • Different materials affect the absorption of light differently based on their material properties.

    Wave Properties

    • Frequency refers to the number of oscillations or cycles of a wave per second.
    • Amplitude of a wave is defined by its maximum displacement or intensity.
