Photoelectric Effect vs Photovoltaic Effect The ways in which the electrons are emitted in the photoelectric effect and photovoltaic effect create the difference between them. The prefix ‘photo’ in these two terms suggests that both these processes occur due to the interaction of light. In fact, they involve the emission of electrons by the absorption […]
Difference Between Dry Cell and Wet Cell
The key difference between dry cell and wet cell is that in dry cells, either a porous container or mixing with a gel medium restrains the flow of electrolyte whereas wet cells have a fluid and the fluid is free to move. A device that can produce an electromotive force, and subsequently a current as […]
Difference Between Alpha Beta and Gamma Radiation
Alpha Beta vs Gamma Radiation A stream of energy quanta or particles with high energy is known as radiation. It naturally occurs when an unstable nucleus transforms into a stable nucleus. The excess energy is carried away by these particles or quanta. Alpha Radiation (α Radiation) A helium-4 nucleus emitted by a larger atomic […]
Difference Between Pitch and Volume
Pitch vs Volume Loudness and Pitch are characteristics of sounds. Loudness refers to the magnitude of the sound heard, and pitch is related to the frequency of the sound. Loudness, in common terms, is referred as the volume. Pitch and volume are parts of music and sound engineering vernacular, but the term loudness is […]
Difference Between Pulse and Wave
Pulse vs Wave Waves are a very common occurrence in nature. The origin of waves lies in the vibrations. A sudden change in the energy of a system or an object results in an immediate change, in the energy of the surroundings. This energy dissipates through the medium by different mechanisms to restore the […]
Difference Between Peak to Peak and RMS
Peak to Peak vs RMS Peak to Peak and RMS amplitudes are two measures of an alternating signal/source. Peak to peak amplitude is measured from the signal and RMS value has to be derived from the measurements. Peak to Peak Peak amplitude is the maximum amplitude obtained by a signal/source in a given interval. […]
Difference Between Light and Radio Waves
Light vs Radio Waves Energy is one of the primary constituents of the universe. It is conserved throughout the physical universe, never created or never destroyed but transforming from one form to another. Human technology, primarily, is based on the knowledge of methods to manipulate these forms to produce a desired outcome. In physics, […]
Difference Between LiDAR and RADAR
LiDAR vs RADAR RADAR and LiDAR are two ranging and positioning systems. RADAR was first invented by the English during the Second World War. They both operate under the same principle though the waves used in the ranging are different. Therefore, the mechanism used for transmission reception and calculation are significantly different. RADAR Radar […]
Difference Between Moment and Couple
Moment vs Couple Moment of force and couple are two important concepts found in mechanics. These describe the effect and cause of rotation in force systems, particle systems, and in rigid bodies. Moment of a force governs many of the rotational properties of the systems. From a certain perspective, it is the equivalent of […]
Difference Between Tangential Acceleration and Centripetal Acceleration
Tangential Acceleration vs Centripetal Acceleration Acceleration is the rate of change of velocity, and when expressed using calculus, it is the time derivative of the velocity. Tangential acceleration and centripetal acceleration are components of the acceleration for a particle or a rigid body in a circular motion. Tangential Acceleration Consider a particle moving along […]
