In which applications are sound waves reflected? check all that apply. cleaning lenses detecting diseases destroying cancer cells locating damaged parts breaking down kidney stones monitoring fetal development

The correct answers are detecting diseases, locating damaged parts and monitoring fetal development.

Explanation:

Ultrasound is a sound wave with higher frequency. The frequency of ultrasound wave is higher than 20,000 Hz.

Ultrasound is a technology that uses high frequency sound waves to create images.

Sound wave is used to detect the damaged parts in the big machinery plants by sending the sound waves. If the sound wave gets reflected back then there is no flaws in the machine but it is not then there may be some damaged parts or cracks in that machine.

Ultrasound is used in medical imaging technique. The ultrasound machine transmits high frequency sound into body by using probe to get the images of the internal parts of the body. It helps in monitoring fetal development. It detects the diseases in the body like tumor.

Therefore, the applications of the sound waves reflected are detecting diseases, locating damaged parts and monitoring fetal development.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
