True or false! the focal point of a concave mirror is a point on the optic axis through which incident rays parallel to the axis will converge. multiple choice! what is the relationship between frequency and degree of refraction? dispersive media waves of high frequency do not refract at all while waves of low frequency do dispersive media waves of high frequency refract more than do waves of low frequency dispersive media waves of low frequency refract more than do waves of high frequency dispersive media waves of low frequency do not refract at all while waves of high frequency do multiple choice! why was roemer's measurement of the speed of light inaccurate? because man's reaction time was much slower than the speed of light because the eclipses of jupiter's were not regular enough he did not know the accurate diameter of the earth's orbit an object is placed 5.00 cm beyond the focal point of a convex lens whose focal length is 10.0 cm. if the object height is 3.0 cm, calculate the image height.
