The speed of light at sea level is approximately 299,792 kilometers per second (about 186,282 miles per second) in a vacuum. However, in the atmosphere, it slows down slightly due to refraction, but this effect is minimal. The speed remains effectively constant for most practical purposes, and it is often rounded to 300,000 kilometers per second in calculations.

Which of the following forms of light can be observed with telescopes at sea level?
Telescopes at sea level can observe visible light, radio waves, and a small portion of infrared and ultraviolet light that are able to penetrate the Earth's atmosphere. Other forms of light such as X-rays and gamma rays are absorbed by the atmosphere and cannot be observed at sea level.

What is the reference point for altitude?
Mean sea level (MSL) which is the average level of the sea. Determinig "sea level" is a very complex measurement. All other altitude measurements in aviation, in one way or another, are referenced from the mean sea level.
