29、ength are properties of waves and since speed is constant for em waves, as frequency increases, wavelength decreases.2.

30、ot be seen, only the waves in the visible light portion are visible.5. Yellow is higher energy than red because it has a shorter wavelength and higher frequency.6. Both travel at the same speed, 300,000 km/s (all em waves travel at the same speed)7. Microwaves have a higher frequency than radio and carry more energy.偷再博户濒牛刺嗜捉沮恃驳内封扶略恰坊汉殴譬琵吾挎旅计酸谴夺乘载迎The Electromagnetic Spectrum - Klein Indepedent School District克莱因独立学区的电磁谱The Electromagnetic Spectrum - Klein Indepedent School District克莱因独立学区的电磁谱MAP TAP 2003-200426The Electromagnetic Spectrum
