Elements on the right side are non metals, such as Chlorine, Fluorine, Bromine, etc.
Answer:
When experiments are carried out or research is done in a certain field of knowledge the scientist at first hypothesise certain knowledge or make theoretical hypotheses about that field of knowledge.
And then conduct the experiment or research to derive certain conclusions and get answers which they can apply on the hypothesis made or on the previous knowledge they have and thereby confirm or negate the hypothesis.
When two scientists are working on similar experiment and they tend to differ in the conclusions drawn by the result, as they get from experiment then it is called as confirmation bias among the scientists.
Answer
6.9 x 10¹²Hz
Explanation:
Given parameters:
Wavelength of the wave = 4.35 x 10⁻⁵m
Unknown:
Frequency of the wave = ?
Solution:
The speed of a wave is related to the wavelength and frequency using the expression below;
C = Fλ
C is the speed of light = 3 x 10⁸m/s
F is the frequency
λ is the wavelength
Insert the given parameters and solve;
3 x 10⁸ = F x 4.35 x 10⁻⁵
F = 
= 6.9 x 10¹²Hz
