Ahigh school website directs parents to not allow student access to blue laser pointers or allow the students to bring them to school. it includes a video describing the danger inherent in the misuse of all laser pointers particularly the blue laser pointer. why would they claim that blue laser pointers are more of a concern than red laser pointers? a) colored light falls into the visible region and the red light has a smaller wavelength and higher energy than blue light. b) the wavelengths and energies differ. the ultraviolet blue light has a larger wavelength and smaller energy compared to infrared. c) both wavelengths fall into the visible light region but blue light has a smaller wavelength and higher energy than red light. d) these colors have similar wavelengths but the blue laser light has more energy than red laser light making it more dangerous.
