Sea turtle researchers decided to install cameras at a nearby beach to capture images of any turtles that visited the beach during the night. The researchers were careful to select and install cameras that would not be detected by the sea turtles, ensuring they would not be disturbed. Uses and Dangers of the Electromagnetic Spectrum Wave Type Uses Dangers infra-red remote controls, thermal imaging can burn skin micro microwave ovens, communication systems can heat internal body tissue ultra-violet detergents, security marking can cause skin cancer and blindness visible spectrum light sources, optic fibers can cause damage to eyes Which type of electromagnetic waves should the scientists’ cameras use in order to safely capture images of the sea turtles at night?
