Motion and Waves Quiz

Scalar quantity has only magnitude, and distance is a scalar quantity.

Sound waves are classified as longitudinal waves, with particle vibrations parallel to the wave direction.

Mechanical waves, such as sound waves, require a medium for propagation.

Newton's Second Law of Motion is expressed by the equation F = ma.

Hertz is the unit of frequency, measured in cycles per second.

In a transverse wave, particles of the medium vibrate perpendicular to the direction of the wave.

Hertz is the SI unit of frequency, measured in cycles per second.

In transverse waves, the medium oscillates perpendicular to the direction of the wave.

Frequency and wavelength are inversely proportional in a wave.

The speed of light in a vacuum is approximately 3 x 10^8 meters per second.

Newton's First Law of Motion states that objects remain at rest or in uniform motion unless acted upon by an external force.

The period of a wave is inversely proportional to its frequency, expressed by the formula T = 1/f.

Speed is the magnitude of motion, while velocity includes both magnitude and direction.

The Doppler effect is the change in frequency of a wave in relation to an observer's motion.

The equation s = ut + 0.5at^2 describes uniformly accelerated motion.

Diffraction is the bending of a wave as it encounters an obstacle or opening.

Phase in wave terminology refers to the position of a point in the wave cycle.

Sonar technology relies on the reflection of sound waves to detect objects underwater.

Resonance in waves refers to the amplification of vibrations at a natural frequency.

Constructive interference results in the reinforcement of waves, leading to a greater amplitude.
