I’m playing with the optics kit we bought my eldest daughter when she was four. The set contains a diverging lens made out of some kind of glass with index of refraction of about 1.6. The focal length of the lens is |f| = 5cm. One surface of the lens is planar and the other is curved. What is the radius of curvature of the curved surface? Assume light reaches the curved surface first and report the radius of curvature with the correct sign.

(a) 3cm
(b) −3cm
(c) 6cm
(d) −6cm
(e) Toby.

Which statement correctly describes the relationship between frequency and wavelength?

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to.in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?

Could someone me find the answer to this problem.
