Answer:
The hypothesis that Dr. Masood is testing is best described as a (Casual) hypothesis.
Explanation:
A hypothesis is defined as a particular statement of prediction. It is described as concrete rather theoretical i.e what you expect will happen in your research. A single study can have one or more hypotheses.
There are four different types of the hypothesis that can be used in experimental design i.e. directional, causal, null, and non-directional hypotheses.
A causal hypothesis is defined as a theory of how different things interact, and how one thing causes another. The motive of causal studies is to reject or confirm any mentioned causal hypothesis. It defines the cause-and-effect relationship between variables.
Answer:
The Sun emits radiation right across the electromagnetic spectrum, from extremely high-energy X-rays to ultra-long-wavelength radio waves, and everything in-between. The peak of this emission occurs in the visible portion of the spectrum.
Different wavelengths of light generally come from different regions of the Sun’s atmosphere or are due to particular atoms radiating at specific wavelengths (spectral emission lines). Visible light, for example, comes from the photosphere (or surface) whereas most infrared light comes from the lower chromosphere just above. Much of the high-energy UV and X-ray photons come from the Sun’s outer atmosphere (called the corona). This gives astronomers the ability to explore different solar features, constituents or processes simply by selecting a particular wavelength of light to observe. That is why NASA’s Solar Dynamics Observatory, for example, has an array of instruments that cover a wide range of wavelengths simultaneously.
