Q.

Name the artist who painted the image of Germania.

Q.

Sushweta has to send a laser signal to Garima. But she finds out that the signal misses Garima by $4^0$. Suppose the angle of incidence is $X^0$. Then angle between Shweta and Garima in terms of $X^0$ can be represented as:

1. (X+4)⁰

2. (2X-4)⁰

3. (2X+4)⁰

4. (X-4)⁰

Q.

In the given figure if the mirror is rotated by an angle $\theta$ in the clockwise direction, then the angle of incidence becomes equal to:

1. θ

2. X + θ

3. X - θ

4. X

Q. Avinash is observing his image in a plane mirror. The distance between him and his image is 4 m. If he moves 1 m towards the mirror, then the distance between his image and plane mirror will be:​

2. 6 m​
3. 3 m​
4. 1 m​

Q. Match the items given in column I with one or more items with column II

Can form image of objects}\\ & \text{spread over a large area}\\ \text{C. Convex Lens}& \text{3. Used by dentists to see}\\ & \text{enlarged image of teeth}\\ \text{D. Concave Mirror}& \text{4. The image is always}\\ & \text{inverted and magnified}\\ \text{E. Concave Lens}& \text{5. The image is erect and of}\\ & \text{the same size as the object}\\ & \text{6. The image is erect and}\\ & \text{smaller in size than the object.}\end{array}$
