Question

What is the practical application of visibe light, Ultraviolet,and X-ray?​

Answer 1

answer:

1)Practical application of visible light:-

1.Visible light is used to make lasers to use in everything from surgery,to CD players to laser pointers.

2.Visible light waves also make our TV, computer and cell phone screens work.

3.Photodynamic therapy which uses visible light waves is used in the treatment of cancer.

2) Practical application of ultraviolet rays:-

1. Food and drug companies use UV lamps to steralise their products.

2.Suitable doses of Ultraviolet rays cause the body to produce vitamin D, and this is used by doctors to treat vitamin D deficiency and some skin disorders.

2.X-ray's are an integral part of contemporary hospitals and medical centres. It is used for checking fractures(broken bones).

3. X-rays are used in computed tomography (CT) scans which combines X-rays with computer processing to create detailed pictures(scans) of cross sections of the body that are combined to form a three-dimensional X-ray ray image.

4.Mammography is a type of X-ray radiograph that is used to detect breast cancer.

Answer 2

Answer:

Explanation:

Aside from sight, there are other important uses for visible light. We concentrate visible light to make lasers to use in everything from surgery, to CD players to laser pointers. Visible light waves also make our TV, computer and cell phone screens work.
