X - rays
1 Are deflected in a magnetic field
2 Are deflected in an electric field
3 Remain undeflected by both the fields
4 Are deflected in both the fields
Explanation:
X - rays remain undeflected by both the fields.

Assertion : VIBGYOR signifies the seven colours of visible light. Reason : Red colour corresponds to higher frequency and blue colour to lower frequency region.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
When visible light is passed through a prism, it undergoes dispersion and splits into seven distinct colors: Violet (V), Indigo (I), Blue (B), Green (G), Yellow (Y), Orange(O), and Red (R). These colors are arranged in order of increasing wavelength and decreasing frequency, with violet having the shortest wavelength and highest frequency, and red having the longest wavelength and lowest frequency among the visible colors. So option (3) is correct.

The correct order of the wave number of the following radiations: IR, UV, radio waves, X-rays and visible light is
1 X-rays > IR > visible > UV > radio waves
2 radio waves > IR > visible > UV > X-rays
3 X-rays > UV > visible > IR > radio waves
4 UV > visible > IR > radio waves > X-rays
Explanation:
Increasing order of wavelength of EMR: X - rays < UV < Visible < IR < Radiowaves Wavelength is inversely proportional to wave number Decreasing order of wave number of EMR: X - rays > UV > Visible > IR > Radiowaves
