The range of human hearing is 20Hz to 20,000Hz. Ultrasound waves are just sound waves with a frequency above 20,000Hz. When ultrasound reaches a boundary between two media with different densities, some are partially reflected back and...

Waves are vibrations that transfer energy from place to place without matter being transferred. Think of a Mexican wave in a football crowd: the wave moves around the stadium, while each spectator stays in their seat only moving up then...

Medical Imaging | Waves | Physics | FuseSchool If only we were all given a window so a doctor could look inside us when we were ill.Think of the operations that would save! Luckily there are now many ways we can see what is happening...

This video explains the basics of sound and how it is produced, transmitted, and perceived. Explore the physics of sound and acoustics. Acoustics is the study of mechanical waves and how they move through gas, liquids, and solids....

It explains the working of SONAR.

Doodle Science teaches you high school physics in a less boring way in almost no time!

Have you ever wondered about what sound is? How do we hear it? Why is it important? Wonder no more. With Alie Astrocyte as your guide, we go through the physics of sound, how our brain hears it, and why it's important for navigating the...

This video is a detailed explanation of how our eyes and ears work, focusing on the process of vision and hearing. It discusses the different parts of the eye and their functions, such as the cornea, iris, lens, and retina. It also...

Upon viewing the What is Sound video series, students will be able to do the following: Understand that sound is produced when matter vibrates. Explain that sound energy can travel through air, liquids, and solids, which are generally...

It explains the characteristics of sound, namely amplitude, time period and frequency of a vibration. It talks about loudness, pitch and quality of sound.

When you hear the roar of traffic, the bark of a dog, or your teacher's voice, you are experiencing sound. This program uses colorful animations to explore important characteristics of sound, including intensity, loudness, pitch, and...

This is a lecture video explaining how loudspeakers work by utilizing the motor effect, which is when a current-carrying conductor experiences a force when placed in a magnetic field. The video demonstrates this effect on a conductor...

Learn how a radio works, from transmitting electrical energy through radio waves to converting them back into audio for the user to listen to. Understand how signals are encoded and decoded using modulation techniques, as well as the...

This video explores five fun facts about sound.

Overview of interference using the example of sound waves.

If you sing at a wine glass at its exact resonant frequency, you can break the glass without the help of a speaker! Learn the physics behind that.

Helping children relate to the topics they study is what the Real World Science series of videos does best. Real World Science: Sound helps students learn the principles of sound, the range of human hearing and significant terms, as they...

"The Ear

The visible part of the ear is called the pinna. It funnels sound into our e

ars.

The sound waves travel down the ear canal toward
s the eardrum.
The eardrum is a membrane at the end of the ear...

This video engages students by asking questions and showing phenomena that relate to simple harmonic motion. The program provides examples and demonstrations using “singing” glasses, violin and piano sounding boards, oscillations in...

Upon viewing the The Nature of Waves video series, students will be able to do the following: Define waves as traveling disturbances that carry energy through matter or space. Explain that waves do not actually move matter. Instead,...

How do waves behave? Badly? In this video we are going to look at how light and sound waves behave. Before we start, you should know that waves can be transverse or longitudinal. Transmission, reflection, refraction, diffraction,...
