There are three main properties of a wave: velocity, wavelength, and frequency.

[v] Wave velocity is the measure of how fast a wave propagates in a given medium. Its unit is meters per second.
[λ] Wavelength is the distance over which the shape of the wave repeats. It depends on the medium through which the wave travels.
[f] Frequency of a wave refers to how many times (per a given time period) the particles of a medium vibrate when the wave is passing through it. The unit of frequency is Hertz, or 1/second.

Wavelength Formula:
 f = v/λ
​
Where:
λ (Lambda) = Wavelength in meters
v = Wave velocity
f = Frequency (Hz)

### 1/5 — I want my money back

*2024-08-30*

I’m upset to have spent the 3 bucks on this app. Doesn’t compute anything like what anybody might use it for. I’m using it for astronomy, the smallest unit of measurement is a millimeter, despite the fact that most of my work requires the answer in nanometers. And I could do that computation separately, and it’d be fine. But the app doesn’t compute any decimals.

### 1/5 — Crashes every time I try to change a value on my iPhone X

*2018-11-13*

Can’t use this because it keeps crashing as already stated. 
Wish also it had more choice for velocity and a custom velocity can be made.
