Yes; if angle of incidence is zero angle of refraction is zero regardless of index:
sin theta r = (n1/n2) sin theta i
That it has a 90 degree angle and two equal 45 degree angles
The [horizontal] range of a projectile is maximised when it shoots at a 45 degree angle. This is true if air resistance is ignored so that the only force acting on the projectile is gravity.
true or false ? perpendicular lines intersect at an angle of 45
True
True
The critical angle is not the same thing as the angle of incidence. There is a reason the confusion. The critical angle is defined as the smallest angle of incidence which results in total internal reflection. Every plane wave incident on a flat surface has an angle of incidence. That can be any angle. When a wave travels from a dense medium to a less dense medium, there comes an angle of incidence where there is no transmission into the less dense medium. We say then that for an angle of incidence above the "critical angle" the result is total internal reflection. It is also true that with Snell's law, the critical angle is the particular angle of incidence which would result in a 90 degree angle of refraction.
False .According to laws of reflection, the angle of incidence is always equal to the angle of reflection.
Angle of Incidence = Angle of ReflectionThis is only true if the angle of incidence is greaterthan the critical angle.
true or false
is true a 10 angle is cngruent to a 10 angle
Yes. It is so true that if they are side-by-side, you can hardly tell them apart.
Yes, the definition of a right triangle is that it has a 90 degree angle
Yes, it is true that angle 60 degrees has two edges in the angle parts.
Those angles are equal at the point where a ray of light hits the mirror,regardless of the shape of the mirror.
Yes it is true that angles that add up to 90 degrees are said to be complementary
That it has a 90 degree angle and two equal 45 degree angles
Type in boolProp allow45DegreeAngleOfRotation true.
