What is the difference between a real and virtual image?

What is the difference between a real and virtual image?

Real images are obtained using a converging lens or a concave mirror. The size of the real image depends upon the placement of the object. A virtual image is an upright image that is achieved where the rays seem to diverge. A virtual image is produced with the help of a diverging lens or a convex mirror.

How many laws are there of reflection?

two laws
There are two laws of reflection.

How do you read a ray diagram?

Step-by-Step Method for Drawing Ray Diagrams

  1. Pick a point on the top of the object and draw two incident rays traveling towards the mirror.
  2. Once these incident rays strike the mirror, reflect them according to the two rules of reflection for concave mirrors.
  3. Mark the image of the top of the object.

How is the angle of reflection calculated according to the law of reflection?

Since the angle of incidence is measured between the incident ray and the normal, so, here the angle of incidence is not 60°. According to the Law of Reflection, θ. i. = θ r. Hence, Angle of Reflection = 60°. Q2: A light ray strikes a reflective plane surface at an angle of 54° with the surface. (i) Calculate the angle of incidence.

How is the law of reflection used in astronomy?

Large telescopes use reflection to form an image of stars and other astronomical objects. The law of reflection states that the angle of reflection equals the angle of incidence, or θ r = θ i θ r = θ i

What is the principle of reflection of light?

The principle when the light rays falls on the smooth surface, the angle of reflection is equal to the angle of incidence, also the incident ray, the reflected ray, and the normal to the surface all lie in the same plane. What is Reflection of Light?

How are right triangles used to prove the law of reflection?

Therefore, we have two right triangles with equal hypotenuses (side AD) and an equal leg. This means that the triangles must be congruent, and θ i must equal θ r, proving the law of reflection. Huygens’ principle uses wavefronts to predict the future position of a wave.
