Blimps are non-rigid airships with an envelope that maintains their shape, while dirigibles are semi-rigid or rigid airships with a structure inside the envelope to maintain their shape. Dirigibles are typically larger and have more internal structure for support and control.

All three are types of lighter-than-air aircraft that rely on buoyancy to fly. They also have a balloon-like structure filled with a gas that is less dense than the surrounding air. However, hot air balloons specifically use heated air to generate lift, while blimps and dirigibles are powered by engines for propulsion.
While balloons are at the mercy of the wind and cannot be steered, dirigibles (or airships) have engines and rudders that allow for controlled navigation and steering. Dirigibles can ascend and descend by adjusting their buoyancy and use their propulsion systems to move in different directions.
The phase difference between two waves is directly proportional to the path difference between them. The phase difference is a measure of how much the wave has shifted along its oscillation cycle, while the path difference is a measure of the spatial separation between two points where the waves are evaluated.
The equation for calculating the phase difference between two waves is: Phase Difference (2 / ) (x) Where: Phase Difference is the difference in phase between the two waves is the wavelength of the waves x is the difference in position between corresponding points on the waves
