|Consider the following statements in the context of 'Holographic Technology'.|
|1. This technique enables only two-dimensional images to be made using the laser.|
|2. This technique is mainly based on the principle of scattering and polarising of light rays.|
|Which of the statement(s) given above is/are correct?|
A) Only 1
B) Only 2
C) Both 1 and 2
D) Neither1nor 2
Correct Answer: D
Solution :[d] Holography is a technique which enables three-dimensional images to be made involving .the use of laser, interference, diffraction, light intensity recording and suitable illumination of the recording. The image changes as the position and orientation of the viewing system changes in exactly the same way as if the object were still present, thus making the image appear three-dimensional.
