When rutherford bombarded thin gold foil with a-particles, he found that some a-particles were deflected through large angles. Which statement explains this deflection?

Matter that emits no light at any wavelength is called

Ascientist notices that an oil slick floating on water when viewed from above has many different colors reflecting off the surface, making it look rainbow-like (an effect known as iridescence). she aims a spectrometer at a particular spot and measures the wavelength to be 750 nm (in air). the index of refraction of water is 1.3
