 sin and cos 30 degrees? sin 30 = 1/2 cos 30 = sqrt 3 /2 What is the sin and cos of 0 sin 0 = 0 cos 0 = 1 What is the sin and cos of 45 degrees .7 transverse wave A transverse wave is a wave that causes vibration in the medium in a perpendicular direction to its own motion. ex: electromagnetic waves (LIGHT) Longitudinal Wave Longitudinal waves are waves that have vibrations along or parallel to their direction of travel. Is a diverging lens and diverging mirrors always have negative or positive focal length? negative What kind of lens or mirror can produce a real image? only a converging lens or converging mirror can produce a real image-->light rays must converge at one point in order to focus the image A convex mirror is converging or diverging? A convex mirror is diverging = DEV - diminished, erect (upright), virtual real or virtual:    o > f REAL If  o > f  the magnification is negative Real or virtual:  o < f image distance will be negative and the image is virtual A convex mirror always produces what kind of image? virtual, because it is a diverging mirror MIRRORS:    Images that are virtual are always in front or behind the mirror? For mirrors images that are virtual are behind the mirror but for a lens, virtual images are found in front of the lens (same side as object) Authorlace.granatelli ID183785 Card SetMCAT physics DescriptionMCAT physics Updated2013-05-23T02:08:37Z Show Answers
