8. incandescent bulb 13. heat 18. false- luminous 19. false- tungsten halogen 26. FM would go to the right of the arrow pointing to the AM station. FM frequencies are higher than AM frequencies. Electromagnetic spectrum is arranged with low frequencies waves to the left and high frequencies to the right. 30. Incandescent light bulb produces the most infrared rays. This type of bulb has low efficiency because it produces relatively little light for the amount of energy it uses.
