Practice Questions:
Example 1: A typical sound wave traveling at 360 m/s has a frequency of 1200 Hz. Find its wavelength. Solution: ν� = 1200 Hz, v = 360 m/s, λ�=? λ=vν=3601200=0.3m�=��=3601200=0.3� Example 2: All electromagnetic waves travel through a vacuum at the same speed. If a wave of frequency 7.5 GHz has a wavelength of 4…

Relationship Between Wavelength and Frequency
The wavelength of a wave is inversely proportional to its frequency. If v represents the velocity of a wave, its frequency f, and its wavelength λ�, then; λ=vf�=�� This means, as wavelength increases, the frequency will decrease and vice versa. In the case of light in a vacuum, this formula is given as λ�=cν

Definitions & Practice Questions
Wavelength and frequency are two important characteristics to explain the nature of a wave. Wavelength is basically the measure of the distance between two successive points referred to as crests or troughs of a wave. It is always measured in the direction of the wave and is represented by the symbol λ�. Since it is…

Solved Examples & Practice Question
When the heat is absorbed by a body, its temperature increases, and when the body discharges or loses heat, its temperature falls. The heat capacity is the heat needed for raising the temperature of an object by a calculation of one degree. It can also be calculated as a ratio of the amount of heat…

The Importance of Gravity
The law of gravity applies to almost everything in the universe. Any two objects pull together like any other two galaxies. In addition, the attractions are small, even zero sometimes, when the distance is large enough. You can find your value in the way all the stories come together. For example, you may have seen…

Formula of Gravity
Gravity or Gravitation is a phenomenon which gives an idea about the existence of a force between any two objects having some mass. The force due to gravity is always attractive. Law of Gravity states that if two masses, m1 and m2, are kept at a distance of r from each other, then force due…

Gravity on The Earth
Gravity is very important to us. It’s impossible to live on Earth without gravity. The gravitational force of the sun keeps the Earth in orbit around it, keeping us far away from the sun and heat. It holds our atmosphere and the air we need to breathe. Gravity is what holds our earth together. On…

Practice Questions
Ans: According to Faraday’s law when the magnetic flux linking a circuit changes, an electromotive force is induced in the circuit proportional to the rate of change of the flux linkage. So, when rectangular coil is rotated in a uniform magnetic field about an axis passing through its centre and perpendicular to the direction of…
