What will be the effect of incident ray of light striking a rough surface compared to the same rays striking a smooth surface?
If the surface is completely reflective then the angle at which the incident light leaves the surface will be different. For a rough surface the light would be scattered, whereas for a smooth surface they would reflect at the same angle the hit. If the surface isn't completely reflective then the angle and speed and which the light enters the object. For a rough surface the angles will random and based on the refractive index of the material. For a smooth surface they will be proportional to the sin of the angle times the refractive index.
Does sound reflect only at 90 Degrees?
No, sound does not only reflect at 90 degrees. Sound waves can reflect at various angles depending on the surface they encounter and the angle of incidence, following the law of reflection, which states that the angle of incidence equals the angle of reflection. Smooth surfaces tend to produce clearer reflections, while rough surfaces can scatter sound in multiple directions.
How is the angle of incidence of light ray related to the angle of reflection?
For a smooth surface, the angle of incidence is the same as the angle of reflection.
A diver shines light up to the surface of a smooth pond at a 10 degree angle some light passes into the air above and the part that reflects back into the water makes an angle of how many degrees?

When light is reflected from smooth surface the angle of incidence is?
The angle between the light ray and the normal (perpendicular) to the surface at the point of reflection.
In which direction do light rays reflecting off a smooth surface reflect?
Newton: " the angle of incidence equals the angle of refraction."
Light rays reflecting off a smooth surface reflect?
Light rays reflecting off a smooth surface reflect in a manner that follows the law of reflection, which states that the angle of incidence is equal to the angle of reflection. This results in a clear and defined reflection of the light source.
What color are mirrors and how do they reflect light?
Mirrors are typically silver in color and reflect light by bouncing it off their smooth surface at the same angle it hits the mirror.
Do light rays reflect many directions on a smooth surface?
Wherever a light ray hits the reflecting surface, the angle of reflection is equal to the angle of incidence. Both angles are measured with respect to the normal (perpendicular) to the surface at that point, so if the surface is bumpy, and the normal to it is different directions in different places, then light rays will reflect in several directions. But if the surface is really a smooth plane, then every light ray that is incident in the same direction will reflect in the same direction. The whole art and science of controlling where reflected light rays go is really the ability to control the shape of the reflecting surface, and the normal to it at different points on it.
Do a chair reflect light?
Yes, a chair can reflect light if it has a smooth and shiny surface, such as metal or polished wood. The reflection will depend on the angle of the light source and the material of the chair.

Explain How water can reflect and refract light?
Water can reflect light because of its smooth surface, which acts like a mirror. When light hits the surface, it bounces off at an angle equal to the angle at which it struck the water. Water can also refract light when it enters at an angle, causing it to change speed and direction as it moves through the water.
Is water a reflector?
Water can act as a reflector for light waves due to its smooth surface and high density. When light hits the surface of water at an angle, it can reflect and create mirror-like reflections.
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 are 3 things that reflect light?
Mirrors reflect light by bouncing it off their smooth surfaces. Water reflects light, especially when the surface is calm and acts like a mirror. Glass windows reflect light depending on the angle of incidence.
What is a very smooth surface able to clearly reflect light to form a virtual image?
A mirror with a very smooth surface can reflect light to form a virtual image. When light waves hit the mirror, they bounce off at the same angle they hit, creating a clear reflection that appears to be behind the mirror, producing a virtual image.
What are the characteristics of things that reflect light?
Things that reflect light typically have smooth, shiny, or polished surfaces that allow light to bounce off of them. Reflective materials are also typically opaque and have a high level of electrical conductivity. The angle of reflection is equal to the angle of incidence when light hits a reflective surface.
