1 Part C Part B Part A Shedding Light on Electromagnetic Waves Name: 1. Fill in the diagram. The Electromagnetic frequency (Hertz)(Hz) = 10 8 = 3. Electricity and magnetism are related. We know this because moving a magnet in a coil of wire produces and an electric current flowing in a coil of wire produces. 4. In the 1860s, James Clerk Maxwell used the data of many experiments to come up with a set of equations which suggested to him that light is an -field wave combined with a -field wave. 5. Draw a 3D electromagnetic wave showing the electric-field wave moving up and down and the magneticfield wave moving out of the page and into the page. electric-field (up and down) magnetic-field (out of the page and into the page) 6. Name three types of waves (other than electromagnetic waves). 7. Using a simple slinky diagram, like the one shown at right, draw: (a) a transverse wave (b) a longitudinal wave (c) Use arrows in your diagrams above to show (a) which way each loop moves and (b) in which direction the wave is moving. Shedding Light on Electromagnetic Waves Page 1 of 5
2 8. All waves, except electromagnetic waves, need a medium to travel through. What is a medium? Give two examples. 9. Label the diagram. 10. In the diagram of the wave above, λ = cm, while the amplitude = cm. 11. Two wave pulses head towards each other on a slinky. Draw what the wave pulses will look like when the two waves meet, and what they will look like after they meet. (when the wave pulses meet) (after the wave pulses meet) 12. What is the frequency (f) of a wave? What is the unit for frequency? speed = distance/time time = distance/speed speed light = 300,000km/s speed sound = 340m/s = 0.340km/s (your units for distance and speed must match: if you use km/s, your distance must be in km) 13. The length of the Earth s equator is about 40,000km. Calculate the time it would take for a light beam and a sound wave to travel (a) around the world once. (b) to the moon. (the Earth-Moon distance = 378,000km) 14. Why do you often hear a thunder clap sometime after you see the lightning? 15. How does a change in frequency of a wave affect its speed? (Hint: TRICK QUESTION) 16. For any given type of wave, a lower frequency results in a wavelength. Shedding Light on Electromagnetic Waves Page 2 of 5
3 Part D 17. Fill in the table using the wave equation: wave speed = frequency x wavelength frequency = wave speed / wavelength wavelength = wave speed / frequency Wave Speed, s (m/s) Frequency, f (Hz) Wavelength, λ (m) Sound in C air Sound in C air He-Ne Laser beam 300,000, x 10-9 m Working-out space Nova FM s broadcast signal 300,000, ,300,000 (100.3MHz) 18.

How are radio waves generated? 21. If a carrier wave looked like this, and the audio signal looked like this, draw the amplitude-modulated (AM) wave that an AM radio station would transmit. (Draw it just below the audio signal.) Shedding Light on Electromagnetic Waves Page 3 of 5
4 Part G Part F Part E 22. FM stands for. 23. Compare and contrast an analogue transmission with a digital transmission. 24. Explain briefly how a microwave oven heats food. 25. Why is infrared light often called radiant heat? 26. Bush fires (or forest fires) present three immediate hazards to humans: ; and; 27. Cold objects produce frequency infrared light, while hotter objects produce frequency infrared light. 28. Describe the operation of a thermal imaging camera. 29. Describe one use of thermography. 30. What is incandescence? 31. In the visible spectrum, red light has the frequency and the wavelength. 32. How are lasers different to other light sources? 33. Label the diagram. Composition of Sunlight Composition of Sunlight Hitting the Earth s Surface (having passed through the atmosphere) (please note: The Earth s atmosphere depicted in the diagram is hugely exaggerated. A scale diagram depicting Earth with a 2cm diameter should have an atmosphere only 0.16mm deep.) Shedding Light on Electromagnetic Waves Page 4 of 5
5 Part I Part H 34. List some of the hazards associated with overexposure to UV. 35. What does SPF30+ mean? 36. Draw a diagram showing the position of the X-ray machine, the body part, and the film (or electronic sensor) when an X-ray photo is taken. Explain what happens. 37. Large doses of X-rays can kill cells. How can this ability be put to good use? 38. Of all electromagnetic waves, gamma rays have the frequency and the wavelength. 39. Steel slabs can be made into thinner sheets by heating them and then feeding them through huge rollers. The rollers can be moved closer together (with a machine) to produce a thinner sheet or moved further apart to produce a thicker sheet. Describe how a gamma ray system can be used to automatically control the thickness of the sheet. steel huge rollers gamma-ray detector radioactive gamma-ray source Shedding Light on Electromagnetic Waves Page 5 of 5
