36. WHAT CAUSES OCEAN WAVES?

37. Waves are most commonly caused by wind.  Wind-driven waves , or  surface waves , are created by the friction between wind and surface water . As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest . These types of waves are found globally across the open ocean and along the coast. 

38. ELECTROMAGNETIC WAVES VISIBLE INVISIBLE - waves that are created as a result of vibrations between an electric field and a magnetic field.

40. WHAT HAPPENS TO THE WAVELENGTH , FREQUENCY AND ENERGY AS YOU MOVE FROM RADIO WAVE TO GAMMA RAY ?

41. INCREASING DECREASING INCREASING INCREASING DECREASING

42. From Radio wave to Gamma ray, the wavelength decreases.

43. From Radio wave to Gamma ray, the frequency decreases.

44. From Radio wave to Gamma ray, the energy decreases.

46. 456 001 What is the relationship between the frequency and wavelength of electromagnetic waves? What is the relationship between wave frequency and wave energy?

47. 456 001 Electromagnetic waves have different wavelengths. The wavelengths of radio waves have multiple kilometers to less thousands of nanometers in gamma rays. Waves in the EM Spectrum vary in size from very long radio waves as the size of that of a building to a very short gamma rays which is smaller than the size of the nuclei of an atom.

48. Wavelength is inversely related to frequency which means that they are opposite in their direction. Frequency is directly related to its energy which means that they have the same direction.

49. Typically, increasing the price of a mango for example during Christmas Eve will result to the lower demand . Whereas, decreasing the price will increasing the demand.

50. However, if the price of the mango increases, the supply of the mango increases. That’s what happened after Christmas Eve.

51. APPLICATION WITHIN AND ACROSS CURRICULUM AREAS

52. WHAT I HAVE LEARNED At this point, let us sum up what you have learned. Choose the right word that will make the statement correct.

53. The electromagnetic spectrum is the arrangement of 1. (Electromagnetic waves, ultraviolet radiation) , which are waves that are created with changing electric field and 2. (electric charge, magnetic field) . EM waves travel on 3. (air, vacuum) at a constant speed of 4. (3 x10 8 m/s, 8 x10 3 m/s) .

54. The electromagnetic spectrum is arranged in a manner of 5. (decreasing, increasing) wavelength, 6. (decreasing, increasing) frequency and 7. (decreasing, increasing) energy. 8. (Gamma ray, Radio wave) has the longest wavelength, lowest frequency, and lowest energy among all EM waves. The 9. (radio wave, visible light) is the only EM wave that can be seen by our naked eye,

55. whereas 10. (red, violet) has the longest wavelength and 11. (red, violet) has the greatest frequency. On the other hand, 12. (gamma ray, radio wave) has the shortest wavelength and highest frequency; which carries the highest 13. (energy, wavelength) among all EM waves. Therefore 14. (gamma ray, radio wave) has the lowest ionizing radiation, while 15. (gamma ray, radio wave) has the highest ionizing radiation.

56. ASSESSMENT Open your modules and complete the 15-item quiz on pages 16-18. Read each question carefully and select the letter that corresponds to the correct answer. Use a separate sheet of paper for your answers.

57. What I can do

58. Make a chart of electromagnetic waves showing the comparison of its size. Cut out pictures of objects or look for things that may represent the size of each electromagnetic wave. On a separate sheet of paper, paste the pictures you have found and arrange them according to the arrangement of EM waves in the electromagnetic spectrum.
