Answer:
The angle between the red and blue light inside the glass is 1.9°.
Explanation:
Given that,
Refractive index
For blue = 1.64
For red = 1.54
Incident angle = 48°
We need to calculate the angle between the red and blue light inside the glass
Using Snell's law
For blue ray,
For red ray,
We need to calculate the angle between the red and blue
Put the value into the formula
Hence, The angle between the red and blue light inside the glass is 1.9°.
Answer:
G. 93 m
Explanation:
Applying the equation of motion,
s = ut + 1/2at²........................ Equation 1
Where s = distance, u = initial velocity, t = time, a = acceleration.
Given: u = 0 m/s ( at rest), a = 3.3 m/s², t = 7.5 s.
Substitute into equation 1
s = 0(7.5) + 1/2(3.3)(7.5)²
s = 0 + 185.625/2
s = 185.625/2
s = 92.8
s ≈ 93 m
Hence the right option is G. 93 m
