What is meant by reflection of light?
Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. For a smooth surface, reflected light rays travel in the same direction. This is called specular reflection.

What is reflection GCSE?
Waves – including sound and light – can be reflected at the boundary between two different materials. The reflection of sound causes echoes. The law of reflection states that: angle of incidence = angle of reflection. For example, if a light ray hits a surface at 32°, it will be reflected at 32°.
What is a reflection in science?
reflection, abrupt change in the direction of propagation of a wave that strikes the boundary between different mediums. At least part of the oncoming wave disturbance remains in the same medium. Regular reflection, which follows a simple law, occurs at plane boundaries.
What is reflection ks2?
When light from an object is reflected by a surface, it changes direction. It bounces off the surface at the same angle as it hits it. Smooth, shiny surfaces such as mirrors and polished metals reflect light well. Dull and dark surfaces such as dark fabrics do not reflect light well.
What is reflection ks2 maths?
Reflection is a type of transformation. To reflect an object, you need a mirror line. When a shape is reflected, its size does not change – the image just appears ‘flipped’. Every point on the shape is the same distance away on the other side of the mirror line.

What is refraction BBC Bitesize GCSE?
Refraction is the change in direction of a wave at such a boundary. It is important to be able to draw ray diagrams to show the refraction of a wave at a boundary. A ray diagram showing refraction at the boundary between air and glass.
What is reflection class 10th?
Hint: Reflection is the phenomenon of bouncing back of the rays of light when they fall on an obstacle. It is similar to the bouncing of a ball when we throw it on a rigid surface. Complete answer: Reflection is the phenomenon of bouncing back of the rays of light when they fall on an obstacle.
