Why is it possible to make a very narrow beam with ultrasound but not with normal sound waves?
Ultrasound can produce a very narrow beam due to its higher frequency and shorter wavelength compared to normal sound waves. The shorter wavelength allows for greater directional control and reduced diffraction, enabling the ultrasound waves to focus more tightly. In contrast, normal sound waves, which typically have longer wavelengths, tend to spread out more as they travel, making it difficult to achieve a narrow beam. This property makes ultrasound particularly useful in applications like medical imaging and industrial testing.
A thin beam of light is?
A ray is a narrow beam of light.
What is the difference between a beam of light and a ray of light?
A light beam or beam of light is a narrow cone of light energy radiating from a small source. In optics, a ray is an idealized narrow beam of light.
What is light beam?
a narrow projection of light energy radiating from a sourse into a beam
How a human can produce ultrasound?
A laser beam pointed at the skin will produce ultrasound as a side effect by interacting with the tissues. This is how a photoacoustic tomography device works and is used for imaging tissues below the skin. "technology works on a near infrared laser that is fired into tissue. The laser's energy, once absorbed by the tissues, generates heat, which in turn generates the photoacoustic signals that are picked up by an ultrasound transducer." coool.
Why is a narrow beam used for breast cancer treatment?
Because the beam can damage other parts of the body and tissue.A narrow beam allows focus on the treatment area with minimal additional damage.
How to build a balince beem?

How does a Polypectomy work?
The polyps are located and removed with a wire snare, ultrasound, or laser beam
Why does an X-ray beam need to be narrow?
X-ray technicians use colimators to narrow the x-ray beam to: - lower the dose the patient gets - lower the effect of scattered radiation
