Both calculators run independently — change the inputs on either side to compare results.

Decibel Calculator (Power Ratio)

Converts a ratio of two power levels into decibels using 10 × log10(P1 ÷ P2). Decibels express how many times larger or smaller one power is than another on a logarithmic scale used in acoustics, electronics, and signal processing.

Wave Properties Calculator

Compute the wavelength of any wave from its speed and frequency using λ = v/f. Works for sound, light, water waves, and any other wave phenomenon — useful in acoustics, optics, radio engineering, and physics homework.
