Question
Physics Question on Ray optics and optical instruments
Given below are two statements:
Statement 1: Image formation needs regular reflection and/or refraction.
Statement 2: The variety in colour of objects we see around us is due to the constituent colours of the light incident on them.
In the light of the above statements, choose the most appropriate answer from the options given below :
Statement I is correct but statement II is incorrect
Statement I is incorrect but Statement II is correct
Both Statement I and Statement II are correct
Both Statement I and Statement II are incorrect
Both Statement I and Statement II are correct
Solution
Statement I is correct. Image formation by lenses and mirrors relies on regular reflection and/or refraction of light.
Statement II is also correct. The color of an object is determined by the wavelengths of light that it reflects. An object appears red because it reflects red light and absorbs other wavelengths.
