The bending occurs because light travels more slowly in a denser medium. As the light enters the water, it is refracted. Since the light is passing from air (less dense) into water (more dense), it is bent towards the normal. The beam of light would appear to bend at the surface of the water.

Which best describes what happens when light traveling through air enters water at an angle? It moves along straight lines in air and changes direction when it enters water.

Simon draws a diagram to illustrate the law of reflection. Which best explains how Simon can correct the error in his diagram? Make the angle of reflection and the angle of incidence equal. Rays of light strike a bumpy road and are reflected.

Regular reflection gives glaze to the eyes, making an object not clear visible. Diffuse reflection makes objects visible. Reflection of sunlight from a metallic car body, silver or gold surfaces are an example of regular reflection. Reflection of light from a stone or asphalt road is an example of diffuse reflection.

: reflection such that the angle of reflection of the light is equal to the angle of incidence and on the opposite side of the normal to the point of incidence.

All Things Equal All reflected light obeys the relationship that the angle of incidence equals the angle of reflection. When the surface of water is wind-blown and irregular, the rays of light are reflected in many directions. The law of reflection is still obeyed, but the incident rays (Fig.

Plane mirrors, convex mirrors, and diverging lenses will always produce an upright image. A concave mirror and a converging lens will only produce an upright image if the object is located in front of the focal point.

Image Characteristics for a Convex Lens

For the concave mirror, when an object is placed anywhere between the focus and infinity the image formed is real and inverted.

The light rays that pass through a convex lens converge or are brought closer together. There are various uses of a convex lens like in a microscope, magnifying glasses, camera, correction of hypermetropia, etc.

Here are some of the most common uses of convex lens.

1. Magnifying lenses. This is actually the most common and the most direct use of magnifying glasses.
2. Eyeglasses. Convex lens are also commonly used in eyeglasses.
3. Cameras.
4. Microscopes.
5. Projector.
6. Uses in Telescope.
7. Multi-junction star cells.
8. Side-view mirror.

Convex mirrors are used inside the buildings, They are also used in making lenses of sunglasses, They are used in the magnifying glass, They are used in securities and they are used in telescopes.

These convex mirrors are used for cars because they give an upright image and provide a wider field of view as they are curved outwards. The convex mirror is also used to provide safety for motorists on roads, driveways and in alleys where there is a lack of visibility.

Mirrors also serve purpose in cameras, specifically digital single-lens reflex (DSLR) cameras. DSLR cameras use mirrors to reflect light from the lens to the viewfinder. Mirrored surfaces are used in architecture and sculpture too – such as the Cloud Gate in Chicago.

Why Cameras Have Mirrors The mirror is used to allow the photographer to see the image through the viewfinder. A system of mirrors reflects the subject to the eye via the viewfinder. The film is exposed to the light and the image is created. Film would later be replaced by a sensor on DSLR cameras.

We use the mirror as we do face-to-face communication: to get feedback on who we are and what we are experiencing in the moment. A quick glance in the mirror reaffirms our sense of self. Mirrors help us regulate our emotions and sync up with ourselves and others. Mirrors simulate face-to-face contact with others.

One mirror is not enough to see yourself as others see you. When you look at a bathroom mirror you see an image of yourself with left and right reversed. If you don’t believe it, extend your right hand to shake hands with yourself. The “person” in the mirror extends his or her left hand.

In normal observers, gazing at one’s own face in the mirror for a few minutes, at a low illumination level, produces the apparition of strange faces. Observers see distortions of their own faces, but they often see hallucinations like monsters, archetypical faces, faces of relatives and deceased, and animals.

When you stare at your eyes in the mirror for a long time in a dimly lit room your brain literally gets bored and it tries to scare you. After a while of staring into your eyes you can see your face all warped and creepy.

Stare into a mirror for several minutes and you may notice your face begin to distort. It could even morph into something downright scary. Seeing monsters in mirrors has long been an effective horror movie device and grist for urban legends.

Body dysmorphic disorder (BDD) is a mental illness where people think they look different to how they really look. BDD is a somatoform disorder. People with BDD may look at themselves in the mirror too much, or some people with BDD may actually try not to look in the mirror.
