1. What is the Distance Between Two Rays Formula?

The formula calculates the distance between two parallel rays of wave energy or light rays at a general point in a medium, accounting for refraction effects as waves propagate from deep water into shallower water.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ b = \frac{b_0}{K_r^2} \]

Where:

\( b \) — Distance between two rays at general point (m)
\( b_0 \) — Distance between two rays at deepwater (m)
\( K_r \) — Refraction coefficient (-)

Explanation: The formula accounts for how wave refraction affects the spacing between parallel rays as they propagate through different water depths.

3. Importance of Ray Distance Calculation

Details: Calculating the distance between wave rays is crucial for understanding wave energy distribution, coastal processes, and predicting wave behavior in nearshore environments.

4. Using the Calculator

Tips: Enter the distance between rays at deepwater in meters and the refraction coefficient. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is wave refraction?
A: Wave refraction is the bending of wave fronts as they approach the shoreline at an angle, causing waves to become more parallel to the coastline.

Q2: How is the refraction coefficient determined?
A: The refraction coefficient is calculated based on water depth changes and wave direction changes as waves propagate from deep to shallow water.

Q3: What are typical values for the refraction coefficient?
A: Refraction coefficient values typically range from 0.5 to 1.5, with values greater than 1 indicating wave convergence and values less than 1 indicating wave divergence.

Q4: Why does ray spacing change with refraction?
A: As waves refract, the distance between adjacent wave rays changes due to variations in wave speed and direction across different water depths.

Q5: What applications use this calculation?
A: This calculation is used in coastal engineering, wave energy studies, harbor design, and shoreline management to predict wave patterns and energy distribution.
