1.A telescope is a tool that helps people observe distant objects. In the simplest telescope design, incoming light hits a lens and is focused to a single point. This focused image is then magnified by a second lens so that it is roughly the same size as an observer's pupil. Which of the following wave behaviors plays the most important role in the functioning of this type of telescope?
Group of answer choices

reflection

resonance

refraction

interference

2.Pick the THREE statements that describe convex lenses.
