The scientific method is limited to investigating physical phenomena that are which of the following? select all that apply. observable repeatable falsifiable unique measurable

Observable

Repeatable

Falsifiable

Measurable

Explanation:

It should be understood that the scientific method cannot be used to provide proofs to unique historical events which are not repeatable. If you were asked to prove that the first atomic bomb was dropped over the city of Hiroshima, Japan, you would not be able to devise an experiment which could recreate the actual event. The scientific method, therefore, is limited or restricted to investigating those physical phenomena that are:

observable;

measurable;

repeatable;

falsifiable.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.

one part of the electromagnetic spectrum that arrives on earth as solar radiation from the sun is the visible spectrum. wavelengths of the visible spectrum combine to form what we refer to as

answer - d) ultraviolet radiation.

violet /   380–450 nm / 668–789 thz

violet is number 1 in the chart of visible light.
