Types of Waves: . Transverse waves . Compression/Longitudinal Waves www.splung.com
Parts of A Transverse Wave: Crest: Top of wave Trough: Bottom of wave Wavelength: Measure of the distance between two crests or troughs Amplitude: Distance from the rest position to the crest/trough Frequency: Number of waves that pass a certain point in a certain amount of time. Speed:Distance a wave travels in a amount of time Parts of A Compression Wave: Compression-Part of the wave that is pushed together Rarefaction-Stretched out part of waves sciencewaveproperties.weebly.com
Mechanical Waves: .Has to have a medium to travel .Can be a transverse or compression wave .Travel slower than E.M. waves Electromagnetic Waves: .Can travel through empty space .All travel at the same speed through empty space .Can travel at the speed of light .Transverse Waves Both: .Can't transmit matter .Transverse waves www.youtube.com Here The Difference Between Mechanical and Electromagnetic Waves is demonstrated using a vacuum, a bell jar, and 2 common cell phones.

Behaviors of Waves: Refraction: Bending of waves caused by a change in their speed as they pass from one medium to another. Reflection: Bouncing back of a wave when it meets a surface or boundary that does not absorb the entire wave’s energy. Transmission: When waves pass through a given point or medium. Absorption: Occurs when the energy of certain frequencies of light is not transferred through, or reflected by the given medium. education-portal.com
Color and Color Filters Color: The color we see depends on the color of light that is shined on the object, and the color of light that is reflected by the object.If all colors of light are reflected, it will appear white. If all colors of light are absorbed, it will appear black. Color Filters: Allow only certain colors of light to pass/transmit through them. They absorb or reflect all the other colors. azizonomics.files.wordpress.com
Parts of the Ear Outer Ear: Sound waves are gathered in the outer ear, which is shaped to capture sound. Middle Ear: Vibrations transmitted from the ear drum to the three small bones (hammer, anvil, stirrup), which transmit the vibrations to the inner ear. Inner Ear: Vibrations in the liquid of the inner ear cause tiny hairs to vibrate. The tiny vibrating hairs transmit energy to nerves attached to the hair. The nerve impulses are transmitted to the brain and interpreted as hearing. www.childrensuniversity.manchester.ac.uk How the Ear Works - The Children's University of Manchester
Parts of The Eye Cornea: The clear outer part of the eye's focusing system located at the front of the eye. Iris: The colored part of the eye that regulates the amount of light entering the eye. Pupil: The opening at the center of the iris. The iris adjusts the size of the pupil and controls the amount of light that can enter the eye. Lens: A clear part of the eye behind the iris that helps to focus light, or an image, on the retina. Retina: The light sensitive tissue lining at the back of they eye. The retina converts light into eletrical impulses that are sent to the brain through the optic nerve. Optic Nerve: A bundle of more than one million nerve fibers that carries visual messages from the retina to the brain. www.childrensuniversity.manchester.ac.uk How the Eye Works - The Children's University of Manchester
Electromagnetic Spectrum Gamma Rays: The most dangerous of the E.M. radiations. It is used in nuclear medicine, and the Gamma Ray Background. X-Ray: Used in dental x-rays, CT scan and Supernova detection. Ultraviolet: Causes skin cancer; and frogs are sensitive to it. Visible Light: Light you can see. Infrared: Radiation is used, in some television controls, night vision photography, and sea surface temperature imaging. Microwave: Radiation is used to cook food by heating water molecules in food, and to detect sea ice with satellites. Radio: Used in AM, FM signal; in RFID tags, etc. www.youtube.com Science expert Emerald Robinson explains what the electromagnetic spectrum is.To view over 15,000 other how-to, DIY, and advice videos on any topic, visit ht...
