Answer:
1. The incident ray, refracted ray, and the normal lie on the same plane.
2. According to Snell’s law of refraction, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant.
Explanation:
The two laws followed by a beam of light as it transfers through two media are as follows:
1. The incident ray, refracted ray, and the normal lie on the same plane.
2. According to Snell’s law of refraction, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant.
Answer:
Option B will save him $1,000
Explanation:
The total expenditure for going to college for two years first and then attending college for 2 years is $83000
The total expenditure for attending university for four years straight is $82000
Calculation:
Going to college for two years then university for two years = no scholarship for college and university= $83000
Going to university = scholarship grants = 20500( deducting scholarship grants of $10000 per year*4) *4= $82000
Savings =
This quotation adds credibility to the text basically because the experience he got when he lived at Ellis Island for three days, is consistent with Freedman's statement that families were scared of the physical examinations.
"We lived there for three days - Mother and we five children, the youngest of whom was three years old. Because of the rigorous physical examination that we had to submit to, particularly of the eyes, there was this terrible anxiety that one of us might be rejected."
