1. You're buving a telescope and trying to choose between two different models. One
model uses a 130 mm diameter mirror to focus the light, and the other model has a.
150 mm mirror. Which model will give you better resolution? What is the smallest
angular separation that could be resolved by your chosen telescope for light at a
00:52
wavelength of 580 nm?
2. Consider two beams of light. The first beam has a wavelength of 280 nm with an
intensity of 3.50 Wm? and the second has a wavelength of 175 nm with an
intensity of 120 W/m? Each beam strikes an identical metal surface, causing
electrons to be emitted. Do the following:
• Determine which beam will eject electrons with more kinetic energy. Defend
your answer!
• Find the energy in el of a photon of this light.
3. Schrödinger's4,20 kg cat is running across the yard with 325 I of kinetic energy.
What is this cat's de Broglie wavelength?
