Why a side mirror is never a concave mirror?
A concave mirror would focus the light back towards the focal point of the mirror. You would not be able to use the mirror effectively with a concave.
How can you use a mirror to signal a friend in the house across the street?
You can point a mirror towards the sunlight, which would cause the light to reflect off the mirror, and if the mirror is tilted to a position towards your friends house, then the light will bounce off into his/her house.
Why should you never point a microscopes mirror directly at the sun?
Think about it. If looking at the sun with the naked eye burns enough, why would u try it with a telescope?
What will be the speed of image if object moves towards plain mirror?
The same speed: the image will always appear to be at a point exactly behind the mirror as the object is in front.
Where should the object be placed in order to produce a larger object behind a concave mirror?
The object should be necessarily be placed between the focal point of the concave mirror and the pole of the mirror to produce a larger image(not larger object) behind the concave mirror.
How you called an object in harmonic motion?
When the acceleration is directly proportional to the displacement from a fixed point and always directed towards that fixed point then such an oscillation or vibration is said to be simple harmonic
Are rays perpendicular to the principal axis of a concave mirror converge at or near the focal point?
It should be parallel. Rays "parallel to the principle axis of a concave mirror converage at or near the focal point.
What will be the angle of reflection if a ray of light is incident towards a plane mirror at an angle of 30 degrees with the mirror surface?
If the ray hits the mirror at an angle of 30 degrees with the mirror surface, the complementary angle that the ray makes with the normal (perpendicular) to the mirror at the point of incidence is (90 - 30) = 60 degrees and since angle of incidence is equal to angle of reflection in a plane mirror, the angle of reflection is 60 degrees.
What Is the focal point of a concave mirror?
It is the point at which light comes to a focus at a single point in space at a certain distance from the mirror relative to its curvature.
What happens when a light ray passes through a focal point and then passes through a covex mirror?
Focal point of which mirror? Because convex mirror would have a virtual focus which is assumed to be at the back of the mirror.
Would the mirror equation work for plane mirrors?
No, it will not, this is because a plane mirror has no focal point. It's rays never converge at a single point like a concave mirror, and therefore it has no focal point The mirror equation is 1/f=1/di + 1/do, where f is the focal point, di is the distance of the image from the mirror, and do is the distance of the reflected object from the mirror. Since focal point is required for the equation, it can't work. Hope this helps.
What is a point of incidence?
The point of incidence is the point where the ray of incidence strikes the mirror.
