COMPARE THE RELATIVE WAVELENGTH OF DIFFERENT FORMS OF ELECTROMAGNETIC WAVES GROUP 2 TO BE DISCUSSED• What is Wavelength? • What is Frequency? • What is Energy? • What is the relationship between frequency and wavelength? • Comparing the wavelength of the different forms of electromagnetic waves WHAT IS ENERGY?Energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. Energy can be neither created nor destroyed but only changed from one form to another. This principle is known as the conservation of energy or the first law of thermodynamics. Frequency and wavelength are inversely proportional to each other. The wave with the greatest frequency has the shortest wavelength. Twice the frequency means one- half the wavelength. For this reason, the wavelength ratio is the inverse of the frequency ratio. The amount of energy they carry is related to their frequency and their amplitude. The higher the frequency, the more energy, and the higher the amplitude, the more energy. WHAT IS THE RELATIONSHIP BETWEEN FREQUENCY AND WAVELENGTH? TO COMPARE THE WAVELENGTH OF THE DIFFERENT FORMS OF ELECTROMAGNETIC SPECTRUM WE BASE ON THE ELECTROMAGNETIC SPECTRUM . THE ELECTROMAGNETIC SPECTRUM IS THE RANGE OF FREQUENCIES (THE SPECTRUM) OF ELECTROMAGNETIC RADIATION AND THEIR RESPECTIVE WAVELENGTHS AND PHOTON ENERGIES. COMPARING THE WAVELENGTH OF THE DIFFERENT FORMS OF ELECTROMAGNETIC WAVES MICROWA VESMicrowave is a form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter corresponding to frequencies between 300 MHz and 300 GHz respectively. MICROWA VES Sourc eVibrating Electrons Uses/ ApplicationsCommunication particularly long- distance radio relay systems (satellite television and communication) microwave ovens INFRAR EDInfrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light. IR is generally understood to encompass wavelengths from around 1 millimeter (300 GHz) to the nominal red edge of the visible spectrum, around 700 nanometers which corresponds to a frequency range from 300 GHz to 400 THz. VISIBLE LIGHT SOURC EVERY HOT OBJECTS USES/ APPLICATIONSVISION, ARTIFICIAL LIGHTING, optical fibers in medical uses, screen of electronic devices. ULTRAVIOLET Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 nm(with a corresponding frequency around 30 PHz) to 400 nm (750 THz), shorter than that of visible light, but longer than X-rays. ULTRAVIOLET Sourc eArcs and gas discharges Uses/ ApplicationsMedical treatments, sanitation process, sterilization, and fluorescence. GAMMA RAY A GAMMA RAY, ALSO KNOWN AS GAMMA RADIATION IS A PENETRATING FORM OF ELECTROMAGNETIC RADIATION ARISING FROM THE RADIOACTIVE DECAY OF ATOMIC NUCLEI. IT CONSISTS OF THE SHORTEST WAVELENGTH ELECTROMAGNETIC WAVES, TYPICALLY SHORTER THAN THOSE OF X-RAYS. WITH FREQUENCIES ABOVE 30 EXAHERTZ (30×1018 HZ), IT IMPARTS THE HIGHEST PHOTON ENERGY. GAMMA RAYS HAVE A WAVELENGTH RANGE BELOW 100 PM. THEY ARE THE MOST ENERGETIC FORM OF ELECTROMAGNETIC RADIATION IN A RANGE GREATER THAN 100 KEV. GAMMA RAY SOUR CENUCLEI OF RADIOACTIVE atoms USES/ APPLICATIONSCANCER TREATMENT, METAL defect detection, beneficial mutations, food preservation WHICH IS WHICH? RADIO WAVES, ON THE OTHER HAND, HAVE THE LOWEST ENERGIES, LONGEST WAVELENGTHS, AND LOWEST FREQUENCIES OF ANY TYPE OF EM RADIATION. GAMMA RAYS- HAVE THE SMALLEST WAVELENGTHS AND THE MOST ENERGY OF ANY OTHER WAVE IN THE ELECTROMAG NETIC SPECTRUM. GAMMA RAYS HAVE THE HIGHEST ENERGIES, THE SHORTEST WAVELENGTHS, AND THE HIGHEST FREQUENCIES. Which has a shorter wavelength? Which has the highest frequency? Which has a longer wavelength? yeYu's The Leaning App ‘ Gz) re e 9 Se ca) vail i AM FM T¥ TY Remote Light Bulb Sun X-ray machine Radioctive Elements eT] The et} Ue itt ois by) Gamma rays 100m im em 0.01¢em 1000nm 40mm O.04nm 0.0001 nm ~ Visible spectrum The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy. As we have observe in the electromagnetic spectrum, radio waves has the longest wavelength but has the lowest frequency therefore it has the lowest energy, on the other hand, Gamma ray has the shortest wavelength but has the highest frequency therefore it has the highest energy.
