+# Wave Formula Calculations
+
+"""
+Background:
+The Wave Formulas are for calculating the characteristics
+of a wave. 
+
+Used for stuff like the:- 
+
+1. Speed of a wave in water
+2. Frequency of wave a in air
+3. Frequency of an electromagnetic - basically like light - wave
+
+Note:- Above are just some of the many cases this formula can be applied to.
+
+This calculator is not really meant for light.
+It can be used for it, just know that you will need to input the speed of light
+again and again because no constant has been assigned to it.
+
+Not sure if this can work for really big numbers.
