12. Danish physicist and chemist who discovered that electric current in a wire can deflect a magnetized compass needle. HANS CHRISTIAN OERSTED GRADE 10 | SCIENCE | WEEK 1 | ELECTROMAGNETIC WAVES P H Y S I C S

13. He formulated a law of electromagnetism, called Ampère's law, that describes the magnetic force between two electric currents. ANDRE-MARIE AMPERE GRADE 10 | SCIENCE | WEEK 1 | ELECTROMAGNETIC WAVES P H Y S I C S

14. He is probably best known for his discovery of electromagnetic induction. MICHAEL FARADAY GRADE 10 | SCIENCE | WEEK 1 | ELECTROMAGNETIC WAVES P H Y S I C S

15. He is best known for the formulation of the theory of electromagnetism and in making the connection between light and electromagnetic waves. JAMES CLERK MAXWELL GRADE 10 | SCIENCE | WEEK 1 | ELECTROMAGNETIC WAVES P H Y S I C S

16. He discovered radio waves and established that James Clerk Maxwell’s theory of electromagnetism is correct. HEINRICH RUDOLF HERTZ GRADE 10 | SCIENCE | WEEK 1 | ELECTROMAGNETIC WAVES P H Y S I C S

21. Me chanical Waves Must travel through a me dium Cannot travel through a vacuum Examples: Sound waves, Ocean waves E lectromagnetic Waves Does not require a medium Can be transferred through a vacuum ( e mpty space ) Examples: Light, UV rays, Visible light GRADE 10 | SCIENCE | WEEK 1 | ELECTROMAGNETIC WAVES P H Y S I C S

22. GRADE 10 | SCIENCE | WEEK 1 | ELECTROMAGNETIC WAVES PHYSICS

23. Wave Crest: The highest part of a wave. Wave Trough: The lowest part of a wave. GRADE 10 | SCIENCE | WEEK 1 | ELECTROMAGNETIC WAVES P H Y S I C S

24. Wavelength: The distance between two consecutive wave crests or between two consecutive wave troughs. Wave Height: The vertical distance between the wave trough and the wave crest. GRADE 10 | SCIENCE | WEEK 1 | ELECTROMAGNETIC WAVES P H Y S I C S

25. Amplitude: The peak (greatest) value (either positive or negative) of a wave. The distance from the undisturbed level to the trough or crest. GRADE 10 | SCIENCE | WEEK 1 | ELECTROMAGNETIC WAVES P H Y S I C S

26. GRADE 10 | SCIENCE | WEEK 1 | ELECTROMAGNETIC WAVES P H Y S I C S

27. The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency and wavelength. Radiation is the term used to describe the transfer of energy in t he form of EM wave. GRADE 10 | SCIENCE | WEEK 1 | ELECTROMAGNETIC WAVES P H Y S I C S

30. WAVELENGTH and FREQUENCY are INVERSELY proportional to each other. FREQUENCY and ENERGY are DIRECTLY proportional to each other. WAVELENGTH and ENERGY are INVERSELY proportional to each other. GRADE 10 | SCIENCE | WEEK 1 | ELECTROMAGNETIC WAVES P H Y S I C S

31. “The longer the __________, the __________ frequency, and the __________ the wavelength, the higher the __________. The energy of a wave is __________ proportional to its frequency but inversely proportional to its wavelength.” WAVELENGTH LOWER SHORTER FREQUENCY DIRECTLY GRADE 10 | SCIENCE | WEEK 1 | ELECTROMAGNETIC WAVES P H Y S I C S
