Question
Modeling the calibration of these objects becomes difficult between 0.01 and 3 candelas per square meter, called the mesopic range. For 10 points each:
[10m] Name these physical objects whose measurements are weighted by either photopic or scotopic efficacy functions. Radiometric quantities do not account for the sensitivity of these objects, unlike photometric quantities.
ANSWER: eyes [or human eyes; prompt on rods or cones or retinas by asking “what larger structure are those part of?”]
[10h] This photometric quantity is equal to the intensity per solid angle of received light. A camera’s exposure value is equal to the base-2 logarithm of this quantity times speed over the reflected-light meter calibration constant K.
ANSWER: luminance [reject “illuminance” or “luminosity”]
[10e] The photopic and scotopic efficacy functions used in photometry reach a peak for respective values of 555 nanometers and 507 nanometers for this quantity, corresponding to visible light.
ANSWER: wavelength [prompt on lambda]
