Question:
Please note decimal place requirements.
Question 1A 6.99 m telescope can gather a given amount of light in 45 minutes. Under the same viewing conditions, how much time would be required for a 2.52 m telescope to gather the same amount of light? Report your answer in hours. Include the unit hr for hour in your answer and report your answer to one decimal place.
Question 2A space based telescope has a 1 m objective, what is the diffraction limited angular resolution of light ( 695 nm)? Report you answer to three decimal point and include the word arcsec as your unit.
Question 3A space telescope had a diffraction limited angular resolution of 0.06" for light (541 nm). What would the angular resolution be for light with a wavelength of 3.2 m? Report your answer to 3 decimal places and include the word arcsec as your unit.
Question 4If you build a telescope with a focal length of 1.09 m, what should the focal length of your eyepiece be if you want a magnification of 75. Give your answer to two decimal places and include the unit centimeter in your answer. Note the eyepiece focal length should be in centimeters.
