Answer
The correct diagram is D. This diagram shows light from the Sun reflecting off Venus and then reaching the Earth, which illustrates how we observe Venus using light.

Answer
A reflecting telescope uses mirrors to gather and focus light, allowing for larger apertures and clearer images. In contrast, the simple telescope used by Galileo primarily utilized lenses, which can result in more optical distortions and limits in light-gathering capability.
Step 4
State the amplitude and wavelength of the wave.
