Question

which type of em wave has the most energy?
o a gamma rays
b microwaves
o c yellow visible light
d green visible light
question 18 (2 points)
a region of space having a gravitational field so intense that no matter or radiation can escape
a high mass star
b black hole
o c luminosity
d low mass star

Explanation:

• For the first question, gamma rays have the highest frequency and shortest wavelength among the given options. According to the formula \(E = h

u\) (where \(E\) is energy, \(h\) is Planck's constant, and \(
u\) is frequency), higher frequency means higher energy.

• For the second question, a black hole is defined as a region of space with an extremely intense gravitational field from which nothing, not even light (radiation), can escape.

Answer:

• First question: a. gamma rays
• Second question: b. black hole
