Explain why a ray of light passing through the centre of curvature of concave minor gets reflected along the same path. The light falling on the centre of curvature is reflected back along the same path because the incident ray falls on the mirror along the normal to the reflecting surface.

It shields our planet from the UV radiations, as these ultraviolet rays are harmful for all the living things. Therefore, any change in the size of this layer will automatically affect the life of people, plants and animals living on earth. Dark reaction of photosynthesis does not need light. Do plants undergo dark reaction at night? Dark reaction does not mean that it occurs in the absence of light i. Infact, it is the reaction occurring simultaneously with light reaction.

It a chemical process occurring independent of light. This reaction is completely based on enzymes. Important Short Answer Type Questions. Here you will get important questions to be prepared for 2 and 3 marks answer type questions asked in CBSE class 10 Science paper. How are we able to see distant and nearby objects clearly? Which part of eye helps in changing curvature of lens? Why no image is formed at blind spot? We can see distant and near objects clearly because of the property of accommodation of eye.

Accommodation is the name given to the ability of the lens of the eye to change its focal length and produce focused images of both distant and near objects on the retina. Ciliary muscle helps in changing curvature of the lens. They are attached to the lens and contract or release to change the lens shape and curvature. No image is formed at blind spot because there are no photo receptors, i.

Define it. Also, the height of object is always positive. So, Magnification will be negative. Similarly, if image is virtual, it will be erect. Thus, convex mirrors enable the driver to view much larger area which is not possible with a concave mirror. Important Long Answer Type Questions. Get here a collection of long answer type questions to be prepared for the 5 marks answer type questions:.

How is the direction of a magnetic field at a point determined? The direction of the magnetic field at a point can be found by placing a small magnetic compass at that point.

The north end of the needle of a compass indicates the direction of magnetic field at a point where it is placed. Inside the magnet, the field lines emerge from the south pole and terminate at the north pole, as shown in the given figure. Explain how antacids give relief from acidity. Write the name of one such antacid. How does the pH will change as it turns to curd?
