Revision Waves and Radioactive radiation. A wave is a disturbance in a medium that carries energy without a net movement of particles You need to know two types: Waves Transverse waves Longitudinal waves Longitudinal and Transverse waves Wave speed Frequecy: How many whole waves that passes a fixed point in a second. Example: What is the wavelength of a sound that is traveling at 343 m/s and has a frequency of 440 Hz?

The wave is in a constant position. Two opposite- facing waves form a standing wave https://alrashidacademykt.blogspot.com/2021/05/ stationary-waves-standing-waves. Bending waves In water we can observe that the waves tend to bend off behind an islet, a pier or the like. This is what allows you to hear sound even if you are behind a corner. Sound is waves that bend around edges and fill in the entire room. Diffraction of Waves | S-cool, the revision website Interference Interference occurs when two or more waves appear in a point and creates a new wave that will in general have new properties such as altered frequency or amplitude.

A mobile phone is essentially a two-way radio that both transmits and receives. Two wavelengths are always used at the same time, one specific wavelength is used to receive, another to send Aurora Borealis About - Aurora Borealis: where to see the Nort hern Lights in 2021? | GoOpti Telescopes Wave emission by elements Red shift and Blue shift Radioactiv e radiation for medical treatment Radon Radon is an invisible and odorless radioactive gas. If you have measured radon levels above 100 Bq/m³, you should take measures to reduce the level. Radon level should not exceed the limit value of 200 Bq/m3. Radon in indoor air increases the risk of lung cancer Fission and Fusion Fission is the splitting of a heavy, Fusion is the process where two light unstable nucleus into two lighter nuclei combine together releasing nuclei. vast amounts of energy Greenhouse effect Carbon Dioxide, Methane, Nitrous Oxide, and the Green house Effect - Conservation in a Changing Climate (lta.o Ozone layer ozone layer – Google Søk Ozone Layer Depletion: Definition, Causes, Effects , & Solutions (sciencefacts.net) UVA, UVB AND UVC + UV INDEX What’s the difference between UVA and U VB rays? | MD Anderson Cancer Center Ultraviolet (UV) Radiation - AIM at Melanoma Foundation Positive effects for being in the sun.
