15 Questions
What is the frequency of a sound wave?
The number of waves passing a given point in the medium each second
What is the amplitude of a sound wave?
The maximum displacement of the air particles from their rest position
What is the wavelength of a sound wave?
The distance between successive compressions
What are regions of high air pressure in a sound wave known as?
Compressions
What is the term for regions in the air where the air particles are spread apart?
Rarefactions
Which of the following best describes the compressions in a sound wave?
Regions of high air pressure
What is the relationship between the frequency of sound and the pitch?
Higher frequency results in higher pitch
How is the wavelength of a sound wave defined?
Distance between successive compressions
What is the amplitude of a sound wave?
Maximum displacement of air particles from their rest position
In a sound wave, what are rarefactions?
Regions of low air pressure
According to the Law of Reflection, the angle of reflection equals to the angle of incidence and the rays travel in the plane of incidence. This law governs the reflection of light-rays off smooth conducting surfaces. Who proposed this law?
Isaac Newton
What is the property of optical media characterized by?
Index of refraction
Snell's law describes the behavior of light when it passes through variations in matter. What quantity changes as light passes from one medium to another?
Speed
What is the index of refraction of vacuum?
1
Which law states that the incident ray, reflected ray, and normal to the surface all lie in the same plane?
Law of Reflection
Learn about the biophysics of the auditory system, including the behavior of pressurized sound waves and the role of hair cells as specialized receptors in the cochlea. Understand how sound is a mechanical wave resulting from the vibration of particles in a medium.
