1 \(\gamma\)-waves
2 Ultrasonic
3 X-rays
4 \(\alpha\)-rays
Explanation:

X-ray will not show the phenomenon of:
1 interference
2 deflection by electric field
3 diffraction
4 superposition
Explanation:
B X-ray will not show the phenomenon of deflection by electric field because it is a electromagnetic waves so they will remains undeflected in an electric field.

A glass rod rubbed with silk is used to change a gold leaf electroscope and the leaves are observed to diverge. The electroscope thus charged is exposed to \(\mathrm{X}\) - rays for a short period. Then
1 the divergence of leave will not affected
2 the leaves will diverge further
3 the leaves will collapse
4 the leaves will melt
Explanation:
B The charge on the glass rod is positive, so the charge on gold leaves will also be positive. Due to \(x\) rays, more electrons from leaves will be emitted, So leaves becomes more positive and diverge further.

The Cutoff wavelength of \(X\)-rays coming from an X-ray tube depends on the .
1 filament material
2 acceleration voltage
3 target material
4 temperature of the filament
Explanation:
B The cut off wavelength of X-rays coming from an X-ray tube depends on the acceleration voltage.

Infrared radiation was discovered in 1800 by :
1 William Wollaston
2 William Herschel
3 Wilhelm Roentgen
4 Thomas Young
Explanation:
B In 1800, William Herschel conducted an experiment measuring the difference in temperature between the colors in the visible spectrum. He placed thermometers within each color of the visible spectrum. The results showed an increase in temperature from blue to red. When he noticed an ever warmer temperature measurement just beyond the red end of the visible spectrum, Herschel had discovered infrared light.
