(a) Spectrometer uses a fiber optic cable to connect the lens and spectrometer (see figure below). Explain why the light collected by the lenses can transfer to the spectrometer via the fiber optic cable? Fiber Optic Lens Cable Spectrometer You need 5 V to charge your smart phone, but you only have an 8 V battery, so you need to make a voltage divider. You use two resistors to make this divider. The first resistor is 300 Q that is larger than the second resister. What value of the second resistor you will use? (b) A camera lens has focal length of 50-mm. We used this camera to take a photo of an object 5 m away from the camera. What is the image position? (c)
