Question
Which lists the correct steps that occur when using a diffraction grating to bend light?
diffracted wavelengths reach the eyes different wavelengths of light bend at different angles the eyes see different colors light strikes the grooves
different wavelengths of light bend at different angles light strikes the grooves diffracted wavelengths reach the eyes the eyes see different colors
diffracted wavelengths reach the eyes the eyes see different colors light strikes the grooves different wavelengths of light bend at different angles
light strikes the grooves different wavelengths of light bend at different angles diffracted wavelengths reach the eyes the eyes see different colors

Once started, why can nuclear fission continue to occur on its own?
The thermal energy released can cause the products to join.
The neutron formed by the reaction can cause more nuclei to combine.
The thermal energy released can cause the products to split.
A neutron begins the reaction, and more neutrons are formed in it.,
