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.

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.
