What are Gamma Rays?
True or False, X-Rays can penetrate lead.
What is False.
How does the wavelength of radio waves compare to visible light?
Radio wavelengths are much longer
Uses of infrared rays
What are thermograms, thermal imaging, remote controls, etc?
Why do x-ray techs protect themselves from exposure to x-rays?
What is X-rays are high frequency, high energy waves that can damage cells and tissues.
Why can radio waves can pass through clouds and dust?
True or False: Most Infrared Rays get absorbed by the Earth's Atmosphere.
What is TRUE.
Why must X-ray and gamma-ray telescopes be placed in space?
What is these wavelengths can’t penetrate the atmosphere, so ground-based telescopes can’t detect them
Why can radio telescopes operate even during bad weather when optical telescopes cannot?
What is radio waves can pass through clouds, rain, and dust, while optical light is blocked or scattered.
