An object with a height of 3.92mm is a distance of 27.3cm to the left of lens f₁ with a focal length of -25.5cm. At a distance of 75cm to the right of lens f₁ is lens f₂ with a focal length of 39.7 cm. Determine the magnitude of the height, h, of the final image (in mm). Question 23 1 pts Space Ship A is approaching Earth from the left at a speed of 0.61c relative to earth. Space Ship B is approaching earth from the right at a speed of 0.55c relative to Earth. Space Ship A emits light of wavelength 715nm as seen on board Space Ship A. When this light is observed by Space Ship B, what wavelength does Space Ship B observe (in nm)? Question 24 1 pts A proton has a speed of 35.3km. What is the energy of a photon that has the same wavelength as this proton (in keV)?
