Students use an optical bench setup (similar to the image below) to explore how the focal length of a lens affects the distance and magnification of images. & ll • 10 20 30 40 They have been tasked with determining the focal lengths and image magnification for two lenses using their optical bench. The students collect the following measurements: Lens A Lens B 6cm 6cm 30cm 30cm Object height Object distance Image height Image distance RIA 2 2 60cm 30cm LOIS LOID 6cm 6cm Object height Object distance 30cm 30cm Image height ? ? Image distance 60cm 30cm Focal length 2 ? Choose the answer that demonstrates the correct relationship between lenses A and B in terms of focal lengths and image height and identify whether the image will be upright or inverted? O Focal length: Lens A > Lens B; Image height: Lens A > Lens B; upright image Focal length: Lens A > Lens B; Image height: Lens A > Lens B; inverted image o Focal length: Lens A <Lens B: Image height: Lens A<Lens B; upright image C Focal length: Lens A < Lens B: Image height: Lens A <Lens B: inverted image

Part A When ultraviolet light with a wavelength of 400 nm falls on a certain metal surface, the maximum kinetic energy of the emitted photoelectrons is 1.10 eV. What is the maximum kinetic energy Ko of the photoelectrons when light of wavelength 310 nm falls on the same surface? Use h = 6.63x10-34 J·s for Planck's constant and c = 3.00x10 m/s for the speed of light and express your answer in electron volts. View Available Hint(s) 10 AED ng ? Ko = eV
