Questions & Answers

Q: What are the three properties of the wave class?

The wave class has three properties: amplitude, period, and phase, which define the shape and behavior of the sine wave being graphed.

Q: How can you calculate the y value for any given x position in a sine wave?

The y value for a specific x position in a sine wave can be calculated using the sine function formula with the given amplitude, period, and phase values.

Q: How do multiple sine waves combine to create complex wave patterns?

By adding together the y values calculated for each individual wave at the same x position, multiple sine waves can create intricate and varied wave patterns.

Q: What is the significance of updating the phase of each wave in the animation?

Adjusting the phase of each wave allows for dynamic animation as the waves oscillate at different points along their cycles, creating motion in the graphical representation.
