What is the angle of reflection if the angle of incidence is 30 degree?
Explanation: The angle between the mirror and the incident ray is 30 degrees. The sum of the angle of incidence and this angle (30) makes a right angle. So, the angle of incidence is 90 – 30 = 60 degrees.
What is the angle of reflection if the angle of incidence is 45 degree?
90 degree
What is the angle of reflection if the angle of incidence is 40 degree?
If the angle between the incident ray and mirror is 40 degree , then the angle of incidence will be 50 degree. Then the angle of reflection will 50 degree ( angle of incidence = angle of reflection).
What is the angle of reflection if the angle of incidence is 60 degree?
Since, angle of incidence = angle of reflection = 30 degrees. The incident ray will have an angle of reflection of 30 degrees (made with a surface normal to the mirror surface). The reflected ray will make an angle of 60 degrees (90 – 30 degrees) with the mirror surface.
What will be the angle of reflection when angle of incidence is 80?
If the angle of incidence is 80 degree the angle of reflection with respect to the normal drawn perpendicular at the point of reflection will be also 80 degree. This is because as per the law of reflection, angle of incidence is equal to the angle of reflection.
How do you relate angle of reflection and angle of incidence what will be the angle of reflection when angle of incidence is 60 Zero degrees?
So, the angle between incident ray and mirror will be 30∘
What is the angle of reflection if the angle of incidence is equal to 75 degrees?
The angle made by the normal will be 90 – 75 = 15. Angle made by normal is equal to angle of incidence. So i = 15 degree. And by the law of reflection which states that angle of incidence is equal to the angle of reflection, the angle of reflection will be 15 degree.
What is the angle of reflection if the angle of incidence is equal to 15 degrees?
Answer. 15=angle of reflection.
What is the angle of reflection if the angle of incidence is 50?
100 degrees
What will happen to the angle of reflection when the angle of incidence is increased?
As the angle is increased to greater and greater angles, we would begin to observe less refraction and more reflection. That is, as the angle of incidence is increased, the brightness of the refracted ray decreases and the brightness of the reflected ray increases.
What happens when the angle of incidence is greater than the critical angle?
As the angle of incidence increases, the angle of refraction gets closer to ninety degrees. At any angle of incidence greater than the critical angle, the light cannot pass through the surface – it is all reflected.
Is the angle of incidence directly proportional to the angle of refraction?
However, the angle of incidence is not directly proportional to the and angle of refraction as the line of best fit is not a straight line through the origin.
What is relationship between the angle of incidence and the angle of refraction?
The relationship between the angle of incidence and angle of refraction is explained by Snell’s law, which states that the ratio of the sine of the angle of refraction and the sine of the angle of incidence is always constant and equivalent to the ratio of phase velocities of the two mediums it is passing through.
What is the angle of incidence and angle of refraction?
When a ray of light is incident at normal incidence, (at right angles), to the surface between two optical materials, the ray travels in a straight line. When the ray is incident at any other angle, the ray changes direction as it refracts.
On what factors the angle of refraction depends?
For any given angle of incidence, the angle of refraction is dependent upon the speeds of light in each of the two materials. The speed is in turn dependent upon the optical density and the index of refraction values of the two materials.
What are the values of angle of incidence?
When the light ray is incident normally on plane mirror surface it means the angle between mirror surface and light ray is 90°.
What is angle of reflection for normal incidence?
When a ray of light is incident normally on a plane mirror it means that the angle of incidence is 0ₒ. From the law of reflection, we find that angle of reflection is also 0ₒ. Thus, for normal incidence on a plane mirror, angle of incidence and angle of reflection are 0ₒ.
What is the value of I and R for normal incidence?
Normal incidence implies, i = 0°. Hence, from the second law of reflection, r = 0°.
What are the values of the angle of incidence ∠ I and the angle of reflection ∠ R for a normal incident 90 )?
What is the angle of incidence of a ray if the reflected ray is at an angle of 90 to the incident ray? Ans. The angle of incidence ray will be 45°.
