Where can sinusoidal curves be found?
Sinusoidal curves are found everywhere (literally, everywhere) , since they are waves.
Sound waves, the electromagnetic spectrum and even actual waves in the ocean, all have the form of sine waves. Sound waves and the electromagnetic spectrum waves are invisible to the naked eye, so you might not be aware of them. However, waves affect our lives very much. |
how are Sound waves a form of sinusoidal curves?
Sound waves are an example to prove how sinusoidal waves are involved in our everyday lives.
Although we can't see sound waves with our eyes, we can use an oscilloscope. The oscilloscope was invented by a German physicist Karl Ferdinand Braun in 1897. An oscilloscope can produce a waveform of a sound. |
The pitch of a sound is determined by the wavelength. This relates to the [b] parameter, which controls the wavelength or the frequency of a sinusoidal wave.
The longer the wavelength, lower the pitch. The volume of a sound is determined by the amplitude. This relates to the [a] parameter, which the value changes the amplitude of a sinusoidal curve. The amplitude has a direct relationship with the volume. If the amplitude of a sound wave increases, this affects the volume to increase. |

How does the electromagnetic spectrum relate to sine curves?
Like sound waves, the electromagnetic spectrum are a series of waves that is in a form of a sinusoidal curve.
There are seven different types of waves that are considered to be in the electromagnetic spectrum. They are: - Radio waves - Microwaves - Infrared Radiation - Visible light - Ultraviolet - X rays - Gamma rays These waves are found in various locations, and are used for different purposes. For example, although we can't see it, microwaves are there to cook food in our microwaves. It's the science of waves! |
