Basically
Wave length = speed / frequency
A Detailed Explanation:
Terms and definitions:
l = Wave length: It is the distance in meters of one wave cycle (m)
f = Frequency: The amount of cycles per second (Hz)
v = Speed of propagation: The distance the wave can travel in a unit of time (m/s)
t = Time in seconds (s)
d = Distance in meter (m) between two points
- 3*10^8m/s will be used as the speed of light instead of the standard 2.9979*10^8m/s
- When I write f(Hz) or use similar notation, ( ) means the unit of measure, Ex. it means Frequency in Hertz
- * will be used as the symbol for multiplication
- [ ] will be used for comments
Explanation:
l = v * t [meter = meter * second / second]
Since frequency is only the reciprocal of period time.
Thus f = 1 / t
l = v / f
We can also say,
v = l * f
f = v / l
Sound in standard air pressure = 331.3 m/s
[may vary between 331.3 to 331.7 depending on the assumptions during the tests we will use 331.3 m/s at 0°C with air density of 1.2922kg/m3]
Light or Radio = 300 000 000 m/s [for our purpose]
Radio wave length (m)
l = 300 000 000 / f(Hz)
l = 300 / f(MHz)
Ex. A 2.4GHz radio frequency will have a wavelength of l = 300 / 2400 = 0.125meter
Audio wave length (m)
l = 331.3 / f(Hz)
Ex. A 1kHz audio frequency in standard air pressure will have a wave length of l = 331.3/1000 = 0.331 meter
Relevant topics:
Latency:
Latency normally goes together with speed of propagation of the wave. Latency means the time it takes for a wave to travel from one point to another.
Seconds = meter / (meter / second)
t = d / v
Ex. A radio wave will take t = 100 000 / 3*10^8 = 0.33ms to travel 100km
Ex. The sun is 1.49*10^11 meter away, it will take 1.49*10^11 / 3*10^8 = 496.6s = 8.27 minutes for the light [image of] to rich the earth.
Ex. A space object is 1 light-year away from us. It will take 1 * 365.25[days] * 24[hrs] * 60[min] * 60[sec] = 31 557 600s for light to travel 1 light-year.
The distance will be d = t * v = 31 557 600 * 3*10^8 = 9 467 billion km

What is the tool used to determine pitch in waves?
A wave gauge or wave recorder is the tool used to determine pitch in waves. It measures the height and frequency of waves, which can then be used to calculate the pitch of the waves.
What is the relationship between the length of a tube and the formation of standing waves in a tube?
The relationship between the length of a tube and the formation of standing waves is that the length of the tube determines the specific frequencies at which standing waves can form. When the length of the tube is an exact multiple of half the wavelength of the sound wave, standing waves are created. This phenomenon is known as resonance.
How do you determine the length of a wave base?
The length of a wave base is typically determined by multiplying the water depth by a factor that depends on the type of wave and the shape of the sea floor. In general, for deep water waves, the wave base is about half the wavelength, and for shallow water waves, it's about equal to the water depth. Measurements and calculations based on wave characteristics are usually used to estimate wave base length.
What factor affect wind wave development?
Wind speed, fetch (distance over which the wind blows), and duration of time the wind blows are key factors that affect the development of wind waves. These factors determine the height, length, and speed of the waves generated by the wind.
How does an antenna work to receive and transmit radio signals?
An antenna works by converting electrical signals into radio waves for transmission and vice versa for reception. When an electrical current flows through the antenna, it creates electromagnetic waves that can travel through the air. These waves carry information in the form of radio signals. The antenna's design and length determine the frequency of the radio waves it can send and receive.
