All Flashcards
What is the effect of increasing the amplitude of a sound wave?
The sound becomes louder.
What happens to the speed of a wave on a string if the tension is increased?
The speed of the wave increases.
What happens to the speed of a wave on a string if the mass per unit length is increased?
The speed of the wave decreases.
What is the effect of a higher amplitude wave?
It carries more energy.
What is the key difference between mechanical and electromagnetic waves?
Mechanical waves require a medium, while electromagnetic waves do not.
Differentiate between transverse and longitudinal waves.
Transverse waves: disturbance is perpendicular to wave direction. Longitudinal waves: disturbance is parallel to wave direction.
Compare wave speed in different mediums.
Electromagnetic waves in a vacuum travel at c. Wave speed on a string depends on tension and mass per unit length. Sound wave speed increases with temperature.
What is a wave pulse?
A single disturbance that carries energy.
What are continuous waves?
Periodic disturbances with specific wavelengths and frequencies.
What are mechanical waves?
Waves that need a medium to travel through.
What are electromagnetic waves?
Waves that don't need a medium to travel through; they can travel through a vacuum.
What are transverse waves?
Waves where the disturbance is perpendicular to the direction the wave travels.
What are longitudinal waves?
Waves where the disturbance is parallel to the direction the wave travels.
Define wave amplitude.
The maximum displacement of a wave from its equilibrium position.
