The rate at which the crest of a wave travels, measured in meters per second (m/s).

How is wave speed calculated?

Wave speed = frequency × wavelength (v = fλ).

What happens to waves when they travel from one material to another?

They usually change speed, but their frequency remains unchanged.

What is the relationship between frequency and period?

Frequency (f) is the number of waves per second, while period (T) is the time for one wave to pass a point; T = 1/f.

The spreading out of waves when they pass through a gap or around an obstacle.

What is interference in waves?

What happens when two or more waves meet, which can result in constructive or destructive interference.

What are sound waves?

Mechanical waves caused by vibrations that require a medium to travel through.

What is the speed of sound in air?

About 330 meters per second (m/s).

What is the difference between a real image and a virtual image?

A real image can be formed on a screen, while a virtual image cannot be projected.

The bending of light when it passes from one medium to another.

What is the refractive index?

A measure of how much light slows down in a medium compared to a vacuum.

What are convex lenses?

Lenses that are thickest in the middle and converge light rays.

What are concave lenses?

Lenses that are thinner in the middle and diverge light rays.

What is electric charge?

A property of matter that causes it to experience a force when placed in an electric field.

Materials that allow electric current to flow through them easily.

Materials that do not allow electric current to flow through them easily.

What is an electric field?

A region around a charged object where other charged objects experience a force.

The relationship between voltage (V), current (I), and resistance (R), expressed as V = IR.

What is power in an electrical circuit?

The rate at which energy is transferred, measured in watts (W).

What is the formula for power?

Power (P) = Voltage (V) × Current (I).

What is electromagnetism?

The relationship between electricity and magnetism, where electric currents can produce magnetic fields.

What is electromagnetic induction?

The process of generating an electric current by changing a magnetic field.

A device that converts mechanical energy into electrical energy using electromagnetic induction.

What is the electromagnetic spectrum?

The range of all types of electromagnetic radiation, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

What is the speed of light in a vacuum?

Approximately 300,000 kilometers per second (km/s).

What is the difference between X-rays and gamma rays?

X-rays are produced by fast-moving electrons losing energy, while gamma rays come from radioactive materials.

What is the principle of superposition in wave interference?

The resultant amplitude at a point is equal to the sum of the amplitudes of the individual waves.

What is constructive interference?

When the crest of one wave meets the crest of another, resulting in a larger amplitude.

What is destructive interference?

When the crest of one wave meets the trough of another, resulting in a smaller amplitude.

What is the significance of the angle of incidence and angle of reflection?

They are equal when light reflects off a surface.

What is the purpose of a voltmeter?

To measure the potential difference (voltage) across a component in a circuit.

What is the purpose of an ammeter?

To measure the current flowing through a circuit.

A complete path through which electric current can flow.

What is a series circuit?

A circuit where components are connected end-to-end, so the same current flows through all components.

What is a parallel circuit?

A circuit where components are connected across common points, allowing multiple paths for current.

What is the effect of increasing resistance in a circuit?

It reduces the current for a given voltage.

What is a thermistor?

A type of resistor whose resistance changes significantly with temperature.

What is a light-dependent resistor (LDR)?

A resistor that changes its resistance based on the amount of light it is exposed to.

What is the function of a diode?

To allow current to flow in one direction only.

What is the relationship between charge, current, and time?

Charge (Q) = Current (I) × Time (t).
