Final answer:
Reflecting telescopes do not show a lot of chromatic aberration since they use mirrors that reflect all colors equally, unlike lenses which refract different wavelengths differently.
Step-by-step explanation:
The answer to the student's question is false. Poor-quality reflecting telescopes do not show a lot of chromatic aberration. This type of aberration is mostly associated with lenses, where the index of refraction varies with color (wavelength), causing images of different colors to have different focal lengths. Reflecting telescopes instead use mirrors, which reflect all colors at the same angle, thus chromatic aberration does not occur. The law of reflection is independent of wavelength, which is why mirrors in optical systems such as telescopes do not demonstrate this issue. That being said, reflective telescopes can still suffer from other types of aberrations, but chromatic aberration is not one of them.
