Ultrasound waves are reflected by body organs due to differences in acoustic impedance at tissue boundaries. When ultrasound waves encounter a boundary between tissues with different densities, some of the wave energy reflects back while some continues through, resulting in echoes that are used to create an ultrasound image.

Why are ultrasonic waves partly reflected by body organs?
Ultrasonic waves are partly reflected by body organs due to differences in acoustic impedance between the organ and surrounding tissues. This reflection occurs at tissue interfaces with varying densities, leading to partial reflection of the waves.
Which waves are used in sonography?
Ultrasound waves are used in sonography, also known as ultrasound imaging. These waves are high-frequency sound waves that are emitted from a transducer and used to create real-time images of internal organs and tissues in the body.
What is the Process of recording sound waves to make image of organs?
The process of recording sound waves to create an image of organs is known as ultrasound imaging. During an ultrasound scan, high-frequency sound waves are emitted from a transducer and bounce off internal structures in the body. The returning sound waves are then translated into an image that can be used to visualize organs and tissues in real-time.
What happens when EM waves encounter a material medium?
When electromagnetic (EM) waves encounter a material medium, they can be absorbed, transmitted, or reflected depending on the properties of the medium. The interaction between the EM waves and the medium can result in effects such as refraction, dispersion, or attenuation of the waves as they pass through the material. The behavior of EM waves in a material medium is determined by factors like the frequency of the waves, the composition of the material, and the electrical properties of the medium.
How are ultrasound waves used in medical imaging to visualize internal organs and tissues?
Ultrasound waves are used in medical imaging to create images of internal organs and tissues by sending high-frequency sound waves into the body. These waves bounce off different tissues and organs, creating echoes that are captured by a transducer and converted into images. This allows healthcare professionals to visualize and assess the structure and function of internal organs and tissues without the need for invasive procedures.

Ultrasonic waves are partly reflected by body organs due to differences in acoustic impedance between the organ and surrounding tissues. This reflection occurs at tissue interfaces with varying densities, leading to partial reflection of the waves.
What happens when EM waves encounter a medium?
The energy in the wave is partly transmitted, partly absorbed, and partly reflected.
What is sonolucent area?
is the area where the ultrasound waves cannot be reflected back at a given frequency
Why is ultrasound monitoring of fetuses similar to mapping the seabed?
Reflected sound waves

Person who uses sound waves to make images of the body?
A person who uses sound waves to make images of the body is known as a sonographer or ultrasound technician. They operate ultrasound machines to capture images of internal organs and tissues for diagnostic purposes.
A wave travelling in air falls on glass plate It is partly reflected and partly refracted The phase difference between reflected and refracted wave is?
The phase difference between the reflected and refracted waves is π radians (180 degrees). This means that the two waves are in opposite phases when they interact with the glass plate.

High frequency sound that is used in medicine to form images of the body and its organs is called?
They are known as Overtones. If they are beyond the range of human hearing, they are called ultrasound, or ultrasonic waves.

How does an ultrasound machine detect if a wave has been reflected from near the surface or deeper down in the body?
An ultrasound machine determines the depth of the reflected waves based on the time it takes for the waves to bounce back to the transducer. By measuring the time delay between when the wave was emitted and when it returns, the machine can calculate the depth at which the reflection occurred.
