Definitions & Solved Example Questions
Intensity is a measure of the energy transmitted by a wave. It is the quantity of energy the wave –conveys per unit time over unit area. It is generally measured with units of watts per square metre (i.e., Wm–2). Intensity will depend on the strength and amplitude of a wave. Intensity is represented by I�…

Determining Deceleration Using Speed Difference and Distance
Convert the initial and final speeds to units that will be useful for calculating the Acceleration (meters per second). Next, square the initial and final speeds. Subtract these squares obtained in the previous step as: square of the final speed minus the square of the initial speed. Divide by two times the distance. This is…

Determining Deceleration Using Speed Difference and Time
This is quite simple. First subtract the ending speed from the starting speed. Convert the speed difference to units of speed that are compatible with the Acceleration to be calculated, usually metre per second. If the speed is in miles per hour, convert that speed to metres per second by multiplying kilometers per hour by…

Deceleration Formulas with Solved Examples
Deceleration is a very commonly occurring phenomenon in our daily lives. Anytime we are travelling, we may notice in the vehicle that when we feel moving forward relative to the vehicle, then we are experiencing Deceleration (a slow down of our Velocity). Here, Deceleration is to be considered as a special case of Acceleration whereby…

What Exactly is a Wave?
In a moving medium, a wave is a type of disturbance. Ocean waves flow across a medium, and we can witness their movement from one place to the next. The motion of an object can be described in terms of speed, which describes the item’s velocity. When a source vibrates and disrupts a particle in…

Wave Speed Definition
Consider a ribbon tied to a rope that is flicked up and down. Consider how a waveform in the rope while the ribbon remains in its original place, moving up and down alone. Consider a stone thrown into a tranquil lake. As soon as the stone reaches the water’s surface, it causes concentric ripples. If…

Formula for Wave Speed with Examples
A wave is the propagation of disturbance that transfers energy through matter or vacuum. A wave is characterized by its wavelength, and/or frequency. The frequency of waves is the number of waves passing past a point in unit time (second) and the period of the wave is its reciprocal. Wavelength is the distance traveled by…

Solved Examples & Practice Questions
When two or more forces are acting on a body, then the total of all the forces which causes the resulting effect is the resultant force or net force. As force is a vector, we need to take the vector sum of all the forces to calculate the resultant. A suitable combination of several forces…

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…
