Understanding Waves: Frequency, Speed, and Wavelength Explained
An explanation of wave frequency, speed, and wavelength. Learn how these concepts are related and how to calculate wave frequency. Includes a simulation.
00:00:00 An explanation of wave frequency, speed, and wavelength. Frequency is the rate at which something occurs. Cycles per second are measured in hertz.
🌊 Wave frequency is the rate at which something occurs, measured in cycles per second or waves per second.
⏱️ One hertz is equal to one cycle per second, indicating the number of waves that happen over a specific time.
🌐 A cycle can be measured from a point on one wave to the same point on another wave, such as from crest to crest or trough to trough.
00:01:24 This video explains the concepts of wave frequency, speed, and wavelength. It also demonstrates how to calculate wave frequency using the number of waves and seconds. Includes a simulation.
Frequency of a wave is determined by the number of cycles per second.
The formula to calculate frequency is the number of waves divided by the number of seconds.
Frequency can be calculated even for partial waves.
00:02:45 Learn about waves and how frequency, speed, and wavelength are related. Discover how the source of waves affects their frequency and understand that wave speed remains constant even when frequency changes.
🌊 The frequency of a wave is determined by the source of the wave.
⏩ Increasing the frequency of a wave does not change the speed at which it travels.
🔄 Higher frequency results in more waves per second, but the speed of the waves remains constant.
00:04:11 This video explains how frequency does not affect wave speed in a medium, but is determined by the source. It also demonstrates how wave speed can change when crossing into a new medium.
🌊 The speed of a wave is determined by the medium it travels through, not the source.
🔄 Higher frequency does not mean faster waves.
⏩⏪ When a wave crosses into a new medium, its frequency remains the same but its wavelength changes.
00:05:34 Learn how frequency and wavelength are related using an analogy involving cars and waves. Higher frequency waves have shorter wavelengths, while lower frequency waves have longer wavelengths.
🌊 Frequency of waves is determined by the source of the wave and does not change with wave speed.
🚗 Wavelength of waves is related to frequency and wave speed, with higher frequency waves having shorter wavelengths.
🌉 An analogy involving cars crossing a bridge is used to explain the relationship between wavelength and frequency.
00:06:56 Frequency, speed, and wavelength are interconnected in waves. The frequency is determined by the source, while the wavelength depends on the wave's velocity divided by the frequency.
The frequency of a wave is equal to the speed of the wave divided by the wavelength.
The wavelength is the result of the wave's velocity divided by the frequency.
A wave is created by a source that provides energy at a certain frequency and travels through a medium at a certain speed.
