Twice as large
To rotate a mirror so that a reflected ray rotates through 25 degrees, the mirror should be rotated half that angle, which is 12.5 degrees.
Yes, light travels through a "one way mirror" but only a small part of the light, most of the light is reflected. In fact light will travel both ways through a "one way mirror"!What makes a "one way mirror" appear to act one way is if the room on one side is brightly lit and the room on the other side is dimly lit, in the brightly lit room the reflected light from the brightly lit room swamps out the small amount of transmitted light from the dimly lit room and the mirror appears to be an ordinary mirror, but in the dimly lit room the transmitted light from the brightly lit room swamps out the small amount of reflected light from the dimly lit room and the mirror appears to be a window.
- light reflected from a window- light reflected from a mirror- light reflected from snow
It becomes magnified with a concave mirror
Direction. When a wave is reflected from a mirror, its direction changes according to the law of reflection, which states that the angle of incidence is equal to the angle of reflection.
To rotate a mirror so that a reflected ray rotates through 25 degrees, the mirror should be rotated half that angle, which is 12.5 degrees.
2*theta
The angle between the incident ray and the reflected ray is equal to the angle between the incident ray and the normal. When the mirror is rotated, the normal also rotates by the same angle. Therefore, the angle between the incident ray and the reflected ray will still be 20 degrees.
A ray of light traveling parallel to the principal axis of a concave mirror will be reflected through the focal point of the mirror after reflection.
That passes through the principal focus of the concave mirror
focus
The mirror is a concave mirror. This behavior is a property of concave mirrors, where parallel rays of light are reflected and converge at the principal focus after reflection.
When light hits a concave mirror parallel to the principal axis, the reflected light rays converge at the focal point of the mirror.
Rays which are parallel to the axis of the concave mirror will converge to the focal point.
The image is reflected from a reflective object, in this case [your mirror], as a Book is not a mirror, it is not reflected.
The index of refraction affects the reflection properties of a mirror by determining how much light is reflected and how much is transmitted through the mirror. A higher index of refraction results in more light being reflected, while a lower index of refraction allows more light to pass through the mirror.
No, your shadow cannot be reflected in a mirror. A mirror can only reflect light that is directly shone on it, whereas a shadow is an absence of light being cast by an object blocking light sources.
