Te whakamāramatanga o te whakaata papatahi
He whakaata papatahi te whakaata he mata papatahi tōna, ā, kua pania tētahi o ōna mata ki te konganuku whakaata kia taea ai e te mata o te whakaata papatahi te whakaata i te neke atu i te 95 ōrau o te mārama e pā ana ki a ia. Ki te whiti koe i te rama ki te mata o te whakaata papatahi, ka whakaatahia e te whakaata papatahi te mārama kia kanapa ai ō kanohi mēnā ka whakaatahia e te whakaata te rama ki ō kanohi. I tetahi atu taha, ki te tū koe i mua i te mata o te whakaata i te awatea, ka whakaatahia e tō mata te hihi o te rā ki te mata o te whakaata, ā, i taua wā anō, ka whakaatahia e te whakaata te mārama ki a koe. Ki te tū koe i mua i te mata o te whakaata papatahi i te pō, ka whakaatahia e tō mata te mārama o te rama hiko.
e anga atu ana ki te mata o te whakaata papatahi, ā, i taua wā anō, ka whakaatahia e te whakaata papatahi te māramatanga o te mārama hiko ki a koe.
Why does your face appear behind a mirror, and what is the process of image formation?
The image formed by the plane mirror
Observe an example of image formation by a plane mirror as shown in the figure. Objects (green) are in front of the surface of the mirror. The object reflects the beam of light towards the surface of the mirror but is drawn as only two narrow or two beams of light. The plane mirror reflects the two rays affecting the surface of the mirror.
The incident light ray 1 is perpendicular or forms an angle of 90o with the normal line (normal line = an imaginary line perpendicular to the surface of the plane mirror that the light passes through)
hence, according to the law of reflection of light, reflected light ray 1 is also perpendicular or forms an angle of 90o with the mirror. The incident light ray 2 forms an angle of 30o with a normal line therefore according to the law of reflection of light; the reflected light ray two also forms an angle of 30o with a normal line.
The light coming from P to the mirror is reflected. When the light is reflected by a mirror, the direction of the reflected light seems to come from P’. If the object is replaced with a flashlight, the light emitted by the flashlight is also reflected by the mirror. The eye of the observer who only saw the reflection of the flashlight and did not know that the light reflected came from P’. The dashed line in the image represents the “path” behind the mirror, and P’ is the image of the object. Because the light does not pass through the plane mirror, the P’s image is a virtual image. If you place the screen at point P, there is no image of the object on the screen.
