Answer:
After refraction at two parallel faces of a glass slab, a ray of light emerges in a direction parallel to the direction of incidence of white light on the slab. As rays of all colours emerge in the same direction (of incidence of white light), hence there is no dispersion, but only lateral displacement.
I think it's 16.8 because you multiply 5.6x3=16.8
there are a reading of something like s-waves and p-waves they tell if an earthquakes coming.
Well for you to get 980 Hz you divided 344 m/s with .35 m
This is triggered by an activity known as heliotropism, or solar tracking. Special motor cells at the bases of the flowerbuds shrink or enlarge as they absorb water, which moves their faces toward the sun.
