What is the principle of superposition in wave interference?
✔✔ The principle of superposition states that when two or more waves overlap, the resulting
wave is the sum of the individual waves' amplitudes.
How does the frequency of a wave relate to its wavelength?
✔✔ The frequency of a wave is inversely related to its wavelength; as the frequency increases,
the wavelength decreases, and vice versa.
What is the role of an electromagnet?
✔✔ An electromagnet generates a magnetic field when an electric current passes through a coil
of wire wrapped around a ferromagnetic core.
How does the Doppler effect explain changes in observed frequency?
✔✔ The Doppler effect describes how the observed frequency of a wave changes due to the
relative motion between the source of the wave and the observer; frequency increases as they
approach each other and decreases as they move apart.

, What determines the buoyant force on an object submerged in a fluid?
✔✔ The buoyant force is determined by the weight of the fluid displaced by the object,
according to Archimedes' principle.
What is the relationship between electric current, voltage, and resistance in Ohm’s Law?
✔✔ Ohm’s Law states that the electric current through a conductor is directly proportional to the
voltage across it and inversely proportional to the resistance.
How does the principle of conservation of momentum apply in collisions?
✔✔ The principle of conservation of momentum states that in a closed system, the total
momentum before and after a collision remains constant, provided no external forces act on it.
What is the difference between a scalar and a vector quantity in physics?
✔✔ A scalar quantity has only magnitude, such as temperature or mass, while a vector quantity
has both magnitude and direction, such as velocity or force.
How do you calculate the average velocity of an object?
