light has the longest wave length
-
Red
-
Violet
Correct Answer
A. RedExplanation
Red light has the longest wavelength among the visible colors. This means that the distance between two consecutive peaks or troughs of the red light wave is greater compared to violet light. Wavelength is inversely proportional to the energy of the light, so red light has lower energy compared to violet light. This is why red light is seen as less intense or brighter compared to violet light.Rate this question:

All stars get their energy from what?
-
Fision
-
Fusion
-
Compression
-
Plasma
Correct Answer
A. FusionExplanation
Stars get their energy from fusion, a process where hydrogen atoms combine to form helium. This fusion reaction releases a tremendous amount of energy in the form of light and heat, which is what makes stars shine. Fission, on the other hand, involves the splitting of heavy atoms and is not the primary source of energy for stars. Compression and plasma are not energy sources but rather states of matter that can exist within stars.Rate this question:

Is the frequency of sunspots predictable?
-
Yes
-
No
Correct Answer
A. YesExplanation
The frequency of sunspots is predictable because scientists have observed a cyclical pattern in the occurrence of sunspots. These sunspots follow an 11-year solar cycle, where the number of sunspots increases and decreases in a regular pattern. This predictability allows scientists to forecast periods of high and low sunspot activity. Additionally, the study of historical sunspot records has provided evidence for the regularity and predictability of sunspot occurrence.Rate this question:

What does E=mc2 predict?
-
Mass conversion
-
The amount of fusion that is made
Correct Answer
A. Mass conversionExplanation
E=mc2 predicts mass conversion. This equation, derived by Albert Einstein, states that energy (E) is equal to mass (m) multiplied by the speed of light (c) squared. It suggests that mass can be converted into energy and vice versa. This concept has been proven in various scientific experiments and is the basis for nuclear reactions and the understanding of the relationship between mass and energy.Rate this question:
