In free space, all components of the complete electromagnetic spectrum have the same

The critical angle of a medium for a specific wavelength, if the medium has relative permittivity 3 and relative permeability \( \frac{4}{3} \) for this wavelength, will be :

Which of the following statements are correct?
A. Relative motion between a coil and a magnet induces the electric current.
B. The charges in motion can experience force due to a stationary magnet.
C. Mutual inductance of a pair of coils does not depend on their separation as well as their relative orientation.
D. Self inductance plays the role of inertia.
Choose the correct answer from the options given below:

In Young's double slit experiment, the light has a frequency \( 12 \times 10^{14} \text{ Hz} \) and the distance between the centres of adjacent fringes is 0.8 mm. If the screen is 1.6 m away, what is the distance between the slits? (Take speed of light \( c = 3 \times 10^8 \text{ m s}^{-1} \))

The reflected and the refracted rays are perpendicular to each other when light is incident on a transparent denser medium having refractive index \( \mu = \sqrt{3} \). The angle of incidence is

An infinitely long straight conductor carries a current of 150 A. At what distance from the conductor is the magnetic field caused by the current equal to \( 10^{-4} \text{ T} \)?

The ratio of nucleus density of nitrogen nucleus (\( {}^{14}_7\text{N} \)) to the nucleus density of oxygen nucleus (\( {}^{16}_8\text{O} \)) will be :

The remainder, when \(5^{60}\) is divided by 7 , is :

Answer the question on basis of passage given below :
The noble gases have closed shell electronic configuration and are monatomic gases under normal conditions. The low boiling points of lighter noble gases are due to the weak dispersion forces between the atoms and the absence of other inter atomic interaction. The direct reaction of xenon with fluorine leads to
of compounds with oxidation numbers +2, +4 and +6.
XeF4 reacts violently with water to give XeO3. The compound of Xenon exhibit stereoisomerism and their geometries can be deduced considering the total number of electrons in the valence shell.
Argon is used in arc welding because it has

Let \(A\) be a \(3 \times 7\) matrix, then each column of \(A\) contains :

The active chemical drug reserpine is obtained from:

The principal value of \(\operatorname{cosec}^{-1} \left(\frac{2}{\sqrt{3}}\right)\) is:

Probability distribution of random variable \(X\) is

X	-2	-1	0	1	2
P(X)	2/11	1/11	4/11	3/11	1/11

Then the value of \(E(X)\) is
