Nuclear radiation Arises from hundreds of different kinds of unstable atoms created in nuclear reactions Ionizing radiation Emitted as unstable items which can damage living tissue. 1. Dr. Nikhat Siddiqi. THE NATURE OF LIGHT. Light is composed of electric and magnetic fields, which . are mutually . perpendicular and which . radiate out from a source. in all directions (Figure . ). . Answer. Radio waves. Microwaves. Infrared. Visible. Ultraviolet. X-rays. Gamma rays.. 2. ) Electromagnetic waves are all.... Longitudinal. Transverse.. Answer. b) Transverse. 3. ) The higher the frequency …. BY. Dr. . Bhawna.

Energy . Energy . exists. in many forms.. Energy . can. be moved from one object to another.. Energy . can. be changed from one form to another.. Energy . cannot. be created or destroyed.. What is Always Present . Ultraviolet (UV) light falls in the range of the EM spectrum between visible light and X-rays. UV . light, which comes from the sun, is invisible to the human eye. .. It . makes black-light posters glow, and is responsible for summer tans — and sunburns. What is Sound Energy?. . is a wave of vibrations that spreads from its source. . As sound travels through a material, the molecules that make it up . . in a kind of pattern. . Energy that travels as a wave through space. Wavelength –. λ – distance between corresponding points on adjacent waves. Frequency – f – waves per second. Spectrum. Breakdown of electromagnetic radiation by increasing wavelength. . Basic Laser Safety Training. 2. Part 1:. Fundamentals of Laser Operation. 3. Laser Fundamentals. The light emitted from a laser is . monochromatic. , that is, it is of one color/wavelength. In contrast, ordinary white light is a combination of many colors (or wavelengths) of light. .
