Solution: The concentration of hydrogen ions is inversely related to its pH and can be measured on the pH scale. Therefore, the more hydrogen ions present, the lower the pH; conversely, the fewer hydrogen ions, the higher the pH.

Initially pH = 3 so,  [H ] = 10^–3.

Now, pH = 6, so, [H ] = 10^–6.

So, the concentration of Hydrogen Ion decreases by 1000 times.

Solution: A revenue deficit, not to be confused with a fiscal deficit, measures the difference between the projected amount of income and the actual amount of income. If a business or government has a revenue deficit that means its income isn’t enough to cover its basic operations i.e. day to day functions of government. To remedy a revenue deficit, a government can choose to raise tax or cut expenses. Similarly, a company with a revenue deficit can make improvements by cutting variable costs, such as materials and labor.

A fiscal deficit is a shortfall in a government’s income compared with its spending. The government that has a fiscal deficit is spending beyond its means. A government creates a fiscal deficit by spending more money than it takes in from taxes and other revenues excluding debt. The gap between income and spending is closed by government borrowing.

Solution: Lens Changes the Refraction Angle, Mirror reflects the Light and Prism has the potential to disperse the Light wave.

Note: The phenomenon of splitting of visible light into its component colors is called dispersion.

Do you know which component of Light has the Maximum Energy or Maximum Frequency? 

Its Violet. Violet waves has the maximum energy because they have the shortest wavelength and the highest frequency in the visible light spectrum.

Ans: (C)

Solution: Formula for Fahrenheit to Celsius conversion is

F= (9/5)XC +32

or, F – 9/5F = 32 (taking F=C)
or, (-4/5)F = 32
or, F = -(32X5)/4
or, F = – 40

Hence, -40 Degree C corresponds to -40 Fahrenheit

Ans: (D)

Solution: Power of the Lens is measured in Dioptre.

The Numerical Value of Power of the Lens (Dioptre) is equal to (1/f), where f is the Focal Length of the Lens. The positive Value of Dioptre shows Convex Lens and the Negative Value shows the Concave Lens.

How will you calculate the Power of the Diode in case two Lenses are joined together?

1/f = (1/f1) (1/f2), where f1 and f2 are the focal length.

Ans: (A)

Solution: When a Sound Wave goes from one medium to another, the frequency remains unchanged.

But why so? 

When a particle travels from one medium to other its amplitude increases on decreases. Further, as the velocity depends on the nature of medium, so velocity also changes. Since velocity changes, wavelength also changes. But the frequency, which is the number of cycles per second remains same.
