Refraction occurs when light waves pass from one medium to another at an angle, causing a change in their speed and direction. The change in speed causes the refracted rays to bend towards the normal line, making them appear smaller in comparison to the incident rays. This bending is a result of the change in speed and wavelength of the light waves as they travel through different mediums.
What else can I help you with?
How do the direction of the original incident ray and second refracted ray compare?
The direction of the original incident ray and the second refracted ray are typically different, as the second ray is refracted in a different manner from the first ray. This is due to the change in speed and angle as light passes through different mediums, causing the rays to bend at different angles.
A plane wavefront is incident normally on a convex lenssketch the refracted wavefront?
When a plane wavefront is incident normally on a convex lens, the refracted wavefront will converge towards the principal focus of the lens. This is because the convex lens causes the light rays to converge, focusing them at a point. The refracted wavefront will exhibit a shape that is curved inward towards the principal focus.
What relationship exist between the intensity of the incident reflected and refraacted rays?
The intensity of the incident ray is equal to the sum of the intensity of the reflected ray and the refracted ray, according to the law of conservation of energy. This means that some of the incident light is reflected and some is refracted when transitioning from one medium to another. The specific ratios of reflection and refraction depend on the properties of the materials involved.
Prove that the angle between reflected and refracted rays is 90 degree if a ray incident from denser to rarer medium?
When a ray of light travels from a denser medium to a rarer medium, the angle of refraction is greater than the angle of incidence. The reflected ray and the refracted ray lie in the same plane as the incident ray. Using Snell's Law and the principle of reflection, we can show that the sum of the angles formed by the refracted and reflected rays with the normal is equal to 90 degrees.
Why can the refracted ray can also be the incident ray?
The refracted ray can coincide with the incident ray when light moves from one medium to another at a 90-degree angle relative to the boundary between the two media. This scenario leads to no bending of the light ray, resulting in the refracted ray following the same path as the incident ray.

When light rays are bent they are called?
When light rays are bent, they are called refracted. Refraction occurs when light passes through different mediums of different optical densities, causing the light rays to change direction.
Do concave lens spread light rays apart?
Yes, concave lenses cause light rays to diverge or spread out. When light rays pass through a concave lens, they are refracted in a way that causes them to spread apart. This results in the formation of virtual images that appear smaller and upright.
What is a copy of an object formed or refracted by rays of light?
Virtual Image
When light passes through a lens what of the light is refracted?
When light passes through a lens, both the parallel rays of light and the converging or diverging rays of light are refracted. The refraction causes the light rays to converge or diverge, which helps in focusing the image on the retina.
Light rays refracted by a concave lens?
A concave lens causes light rays to diverge, creating virtual images that appear smaller than the object. The refraction causes the light rays to spread out, making the image appear further away. This type of lens is used to correct nearsightedness.
What happens to light rays when they hit an object?
They are reflected or absorbed. nope.. they are Refracted
What is a copy of an object form by reflected or refracted rays of light?
Virtual Image
