How is the speed of light affected as light passes at an angle from air to water
2 answers:
The index of refraction of water (1.33) is greater than that of air (1.00).
With that said the index of refraction is related to the velocity of light by:
where n is the index of refraction, c is the speed of light in a vacuum and v is the velocity of light in the medium.
As c is constant we can see that the speed of light in a medium is inversely proportional to the index of refraction
therefore the medium with the lower index of refraction will have the greatest velocity of light (Air).

Answer:
A) The frequency of the dominant allele, C
B) frequency of the heterozygous genotype, Cc
Explanation:
Given -
Curly hair, C, is the dominant allele, and straight hair, c, is the recessive allele
Number of students with curly hair is
Thus frequency of genotype "CC"
Thus, frequency of allele "q"
As per Hardy Weinberg's first equation-
Substituting the value of q, we get -
As per Hardy Weinberg's second equation -
Substituting the values of "p" and "q" we get -
Hence,
A) The frequency of the dominant allele, C
B) frequency of the heterozygous genotype, Cc
