A reflected ray in a mirror makes an angle of 20 and deg with the incident ray. when the mirror is rotated 15 and deg what angle will the reflected ray now make with the incident ray?
The angle between the incident ray and the reflected ray is equal to the angle between the incident ray and the normal. When the mirror is rotated, the normal also rotates by the same angle. Therefore, the angle between the incident ray and the reflected ray will still be 20 degrees.
A light wave was reflected off of a mirror at an angle of 10 degrees What was the incident angle?
The incident angle to the Mirror will be 10 deG.
What will the angle of reflection when the angle between the incident ray and the reflecting surface of the mirror is 30 degree?
You have given the glancing angle as 30 degree. So the angle of incidence = 90-30 = 60 deg As i = r by the law of reflection the angle of reflection = 60 deg
A wave that travels along a boundary separating two mediums?
Very interesting query! Usually it is always possible to retrace the path of light. Suppose a light incident at angle 30 deg in rarer medium ie air it would go with an angle 19.5 deg in a glass medium whose refractive index is 1.5. Now if light traversing form glass incidents at an angle 19.5 deg then it would go refracted with angle of refraction 30 deg. If this is true then in case of ray traversing from denser into rarer at an angle of incidence equal to critical angle, the ray would go along the boundary as the angle of refraction becomes 90 deg. So if we retrace the ray going along the boundary of the two medium then the ray would bend into the denser medium making an angle equal to the value of critical angle with the normal drawn to the boundary line.
What happens to a light wave traveling through air when it strikes a boundary with water at a 45 and Acirc and deg angle?
When a light wave traveling through air strikes a boundary with water at a 45° angle, it will change speed and direction due to a change in the medium's refractive index. This phenomenon is called refraction. The angle of refraction depends on the refractive indices of air and water according to Snell's law.
A reflected ray in a mirror makes an angle of 20 and deg with the incident ray. when the mirror is rotated 15 and deg what angle will the reflected ray now make with the incident ray?
The angle between the incident ray and the reflected ray is equal to the angle between the incident ray and the normal. When the mirror is rotated, the normal also rotates by the same angle. Therefore, the angle between the incident ray and the reflected ray will still be 20 degrees.
A light wave was reflected off of a mirror at an angle of 10 degrees What was the incident angle?
The incident angle to the Mirror will be 10 deG.
The angle between a flashlight beam that strikes a mirroe and the reflected beam is 80 degree what is the angle of incident?
80/2 = 40 deg
What is the angle of incidence of a ray if the reflected ray is at an angle of 90 to the incident ray?
The angle between the incident ray and reflected ray is known as angle of deviation due to reflection. This will always be equal to 2i. Here i is the angle of incidence. So if 2i = 90 then i = 90/2 = 45 So the angle of incidence has to be 45 deg
An angle measures 152 and deg less than the measure of a supplementary angle. What is the measure of each angle?
The first angle is 166 deg and the second is 14 deg.
What will the angle of reflection when the angle between the incident ray and the reflecting surface of the mirror is 30 degree?
You have given the glancing angle as 30 degree. So the angle of incidence = 90-30 = 60 deg As i = r by the law of reflection the angle of reflection = 60 deg
What is the angle of prism?
The bases of a prism are general polygons and can have any angles in the range (0, 360) degrees excluding 180 deg, subject only to constraints imposed by the polygon. The lateral faces are all rectangles (in a right prism) and they meet the bases at right angles.
What is the supplementary angle of 22 digrees?
the supplementary angle of 22 deg = 180-22 = 158 deg.
What is the angle supplementary to the angle measuring 165 12?
180 deg - 165 deg 12 min
What is the supplement of a 16o angle?
Not sure whether the o after the 16 is a typo for 0 or an attempted degree symbol. The supplement of an angle is 180 - the angle. So, if it was 16 deg, the supplement is 164 deg and if it was 160 deg, the supplement is 20 deg.
What is an angle that measures more then 90 degrees?
An Obtuse angle is greater than 90 deg; an Acute angle is less then 90 deg.
What is the angle at a point?
the angle at a point is 0 deg.
