Code Explanation:

Import Required Libraries

import numpy as np

import matplotlib.pyplot as plt

numpy (np) is used for numerical operations and generating data points.

matplotlib.pyplot (plt) is used for visualization.

Generate X-Axis Values

x = np.linspace(0, 10, 400)

np.linspace(0, 10, 400) creates 400 evenly spaced points between 0 and 10.

This ensures a smooth wave curve instead of a jagged one.

Define Two Wave Functions

y1 = np.sin(2 * np.pi * x)       

y2 = np.sin(2 * np.pi * x + np.pi/2)

y1 = sin(2πx): A standard sine wave.

y2 = sin(2πx + π/2): A phase-shifted sine wave (shifted by π/2).

This means y2 leads y1 by 90 degrees, so the two waves are out of sync.

Create the Figure and Plot the Waves

plt.figure(figsize=(8, 5))

Creates a figure with an 8×5 inch size, ensuring a properly scaled plot.

plt.plot(x, y1, label="Wave 1 (sin)", color="royalblue", linewidth=2)

plt.plot(x, y2, label="Wave 2 (sin + π/2)", color="crimson", linestyle="--", linewidth=2)

plt.plot(x, y1, ...): Plots the first sine wave (y1) in royal blue.

plt.plot(x, y2, ...): Plots the second sine wave (y2) in crimson with a dashed (--) line style.

linewidth=2: Makes the lines thicker for better visibility.

label="...": Adds labels for the legend.

Customize the Plot

plt.title("Dual Wave Pattern", fontsize=14, fontweight="bold")

Adds a bold title with a font size of 14.

plt.xlabel("X-axis")

plt.ylabel("Y-axis")

Labels the X-axis and Y-axis.

plt.grid(True, linestyle="--", alpha=0.6)

Adds a grid to improve readability.

Dashed grid lines (--) with a slight transparency (alpha=0.6).

plt.legend()

Displays a legend to distinguish the two waves.

Show the Plot

plt.show()

Displays the final sine wave plot.
