A quantity with magnitude AND direction, e.g. Velocity, Weight and displacement. 1 of 11 What is a SCALAR? A quantity with magnitude only, e.g. Speed, Mass and Distance. 2 of 11 What does SUVAT stand for? SUVAT is an anagram for the words: Distance (S), Initial Velocity (U), Final Velocity (V), Acceleration (A) and Time (T). 3 of 11 What is the FOCUS? The focus is where light waves all converge on one point (the focus) to form a visible image. 4 of 11 What does a CONVEX lens do? A convex lens focuses light waves to a focus. However, they can also magnify or diminish the image. 5 of 11 What are CONVEX lenses used in? Convex lenses are used in: glasses, magnifying glasses, monocles, telescopes, cameras, projectors etc. 6 of 11 What happens to light when is goes through a prism? The light slows down and refracts, meaning that it bends, because of the decrease in speed. 7 of 11 What can REFRACTION be used for? Refraction is very useful for FIBRE OPTIC cabling, binoculars, telescopes and reflectors on bikes. 8 of 11 What are satellites used for? Satellites are used for communications, spying, weather forcasting, etc. 9 of 11 What types of satellites are there? There are three different types of satellites: Geostationary, Low Earth Orbit and Low Polar Orbit satellites. 10 of 11 What is DIFFRACTION? Diffraction is where waves going through a small gap diffract or spread out, forming curved waves. 11 of 11
