An angle of refraction is the angle between the refracted ray and the
2 answers:
Answer: The correct answer is the Normal.
Explanation:
When the incident ray enters the refracting surface, the ray bends from its original path because of the refractive index of the surface.
The angle of refraction is the angle which is made by the refracted ray and the perpendicular on the surface.
The perpendicular on the surface is known as Normal.
Hence, the angle of refraction is the angle between the refracted ray and the Normal.

Answer:
a = 1.41 m/s²
Explanation:
Given that
mass ,m= 41 kg
F₁ = 65 N , θ = 59°
F₂ = 35 N ,θ = 32°
The component of Force F₁
F₁x= F₁cos59° i
F₁x= 65 x cos59° i = 33.47 i
F₁y= - F₁ sin 59° j
F₁y= - 65 x sin 59° j = - 55.71 j
The component of Force F₂
F₂x= F₂ sin 32° i
F₂x= 35 x sin 32° i = 18.54 i
F₂y= F₂ cos 32° j
F₂y= 35 x cos 32° j = 29.68 j
The total force F
F= 33.47 i + 18.54 i - 55.71 j + 29.68 j
F= 52.01 i - 26.03 j
The magnitude of the force F
F=58.16 N
We know that
F= m a
a= Acceleration
m=mass
58.16 = 41 x a
a = 1.41 m/s²
