Explore the fascinating world of wave phenomena with the Doppler Shift Calculator! Perfect for astronomy students, astrophysics hobbyists, and science educators, this app calculates the Doppler shift for light or sound (Δλ/λ = v/c) using relative velocity and wavelength. Toggle between light (c = 3 × 10⁸ m/s) and sound (343 m/s) modes for versatile calculations. With a clean interface and real-time updates, it’s ideal for studying redshift in astronomy or sound pitch changes. Learn about the Doppler effect’s role in understanding the universe.
