Answer:
frequency = 6.12× 10¹⁴ s⁻¹
Explanation:
Given data:
Wavelength = 4.90 ×10⁻⁷ m
Frequency = ?
Solution:
Formula:
<em>Speed of wave = frequency × wavelength</em>
Speed of wave = 3 × 10⁸ m/s
<em>Speed of wave = frequency × wavelength</em>
<em>frequency = Speed of wave/wavelength</em>
frequency <em>= </em>3 × 10⁸ m/s / 4.90 ×10⁻⁷ m
frequency = 0.612 × 10¹⁵ s⁻¹
frequency = 6.12× 10¹⁴ s⁻¹
Answer:
A sugar cube is supposed to be equivalent to a teaspoon of sugar. A teaspoon of sugar is about 4.2 g. Table sugar is composed of sucrose, which is a disaccharide of glucose and fructose, with a molar mass of 342.3 g/mol. This means a sugar cube contains (4.2 / 342.3 =) 0.0123 mol of sucrose, or (0.0123 x 6.022 x 10^23 =) 7.39 x 10^21 molecules of sucrose. As one molecule of sucrose contains one molecule of glucose and one molecule of fructose, then there about 7,400 million, million, million molecules of glucose in a sugar cube.

Answer:
The experimenter observed this experiment in a lab rather than natural world because it might be dangerous to the atmosphere if he does the experiment in the natural world and it was still an hypothesis so that's why he did it in the lab.
Answer:
No because some lights we cannot see because they move to slow or they move to fast for our eye to see. There is just a small little gap compared to what light rays we can actually see. In this picture you can see what I mean.
