Emma notices that the blue sky appears much dimmer at sunset compared to midday.
Which of the following best explains the difference in the brightness and color of the sky?

• The amplitude of the light determines its color, while the wavelength determines its brightness.

• The wavelength of the light determines its brightness, while the amplitude determines its color.

• The amplitude of the light determines its brightness, while the wavelength determines its color.

• Both amplitude and wavelength only affect brightness, not color.

As Sarah watches a tennis match, certain neurons in her visual cortex respond to the movement, shape, and angle of the tennis ball as it flies across the court. These specialized neurons are known as:

• Rods

• Cones

• Feature detectors

• Bipolar cells
