Frequency (y) varies inversely with wavelength (x). Find the frequency (measured in THz ) of blue light if its k value is 175,72
1 answer:
We have been that frequency (y) varies inversely with wavelength (x).
We know that two inversely proportional quantities are in form , where a is inversely proportional to b and k is constant of variation.
Our required equation would be .
To find frequency of blue light, we will substitute and
in our equation as:
Therefore, the frequency of blue light is 764.

Using the z-distribution, the p-value would be given as follows:
b) 0.0086.
<h3>What are the hypothesis tested?</h3>At the null hypothesis we test if the means are equal, hence:
At the alternative hypothesis, it is tested if they are different, hence:
For each sample, they are given as follows:
Hence, for the distribution of differences, they are given by:
.
The test statistic is given by:
In which is the value tested at the null hypothesis.
Hence:
z = -2.63.
Using a z-distribution calculator, for a two-tailed test, with z = -2.63, the p-value is of 0.0086.
Hence option B is correct.
