Questions & Answers

Browse all 4 questions from the The Science of Photography study set below. Each question shows the correct answer — select a study format above to practice interactively.

1 What is chromatic aberration in lenses, from a scientific perspective?

A It is a distortion where straight lines appear curved at the edges of the frame.
B It is the failure of a lens to focus all colors of light to the same convergence point due to variations in refractive index.
C It refers to the loss of image brightness towards the corners of an image.
D It is an electrical interference pattern produced by the camera sensor.

2 How does a Bayer filter array contribute to color imaging in digital cameras?

A It physically blocks all light wavelengths outside the visible spectrum.
B It stabilizes the sensor against vibrations during long exposures.
C It arranges microscopic color filters (red, green, blue) over individual photosites to capture specific color information.
D It enhances the overall sharpness by applying an anti-aliasing filter before image capture.

3 What fundamental optical principle allows a pinhole camera to form an inverted image without a lens?

A Total internal reflection of light within the camera body.
B The diffraction of light waves around the edges of the pinhole.
C The rectilinear propagation of light, where light rays travel in straight lines and converge at a point to form an image.
D The magnetic field generated by the pinhole opening.

4 Scientifically, what primary process is enhanced when increasing the ISO sensitivity on a digital camera sensor?

A The physical size of the sensor's individual pixels to gather more light.
B The signal amplification from the photosites before analog-to-digital conversion, making the sensor more responsive to light.
C The speed at which the lens elements can physically move to achieve focus.
D The chemical reaction rate of a photosensitive emulsion on the sensor's surface.
