In the above formula, the height of the object is taken to be positive, as the object is usually placed above the principal axis. The height of the image is taken to be negative for a real image and positive for a virtual image.

Introduction: In a tug of war, the one applying more force wins the game. In this session, we will calculate this force that makes one team win and one team lose. We will learn about it in terms of balanced force and unbalanced force. Explanation: Force Force is an external effort that may move a […]

The object is located in front of the mirror at a distance of 37.5 cm. Thus, the screen needs to be placed at a distance of 37.5 cm in front of the mirror to get a sharp image.

Introduction: Nowadays magnets are widely used for many applications. In this session, we will discuss the basics of magnets and their properties, and the way they were and are used. Explanation: Magnets: Magnetic and Non-magnetic Materials: Poles of a Magnet: Fig No. 1.2: Poles of a magnet Compass: Interaction Between Magnets: The north pole of […]

The process of converting unpolarised light into polarised light is defined as polarisation. Waves can be polarised through a polariser or polarising filter.

Introduction: We can’t directly observe many waves like light waves and sound waves. The mechanical waves on a rope, waves on the surface of the water, and a slinky are visible to us. So, these mechanical waves can serve as a model to understand the wave phenomenon. Explanation: Types of Waves: Fig:1 Types of waves […]

Introduction: Visible Light: Visible light from the Sun comes to Earth as white light traveling through space in the form of waves. Visible light contains a mixture of wavelengths that the human eye can detect. Visible light has wavelengths between 0.7 and 0.4 millionths of a meter. The different colors you see are electromagnetic waves […]

Longitudinal waves are waves where the particles travel in the direction of motion of the waves. A sound wave is a classic example of a longitudinal wave. They cannot be polarised as they oscillate parallel to the direction of travel.

Transverse waves are waves where the particles oscillate perpendicular to the direction of the wave. These oscillations do not require a medium for propagation. An example of a transverse wave is the ripples on the water’s surface when you throw a rock. Light and all electromagnetic waves can be polarised.

An image is said to be magnified when its size is greater than that of the object and it is said to be diminished when its size is smaller than that of the object. Magnification is a physical quantity used to measure the amount of magnification of an image as compared to an object. In this session we will be looking at the concept of magnification and solve numerical problems based on it.

Electromagnetic waves are transverse waves. Examples such as visible light and microwaves consist of varying electric and magnetic fields that oscillate perpendicular to the direction of propagation. Light is called unpolarised if the direction of the electric field fluctuates randomly. Light sources such as sunlight, LED spotlights, and incandescent bulbs often emit unpolarised light. If the direction of the electric field of light is well defined, it is called polarised light. The most common source of polarised light is a laser.

Polarisation is a phenomenon caused due to the wave nature of electromagnetic radiation. It is an important property of light that affects even those optical systems that do not specifically measure it. The polarisation of light affects the focus of laser beams, affects cut-off wavelengths of filters, and can be important to avoid unwanted back reflections. Read on to learn about polarisation and the two types of waves – Transverse and longitudinal.

An example of polarisation in our everyday life is polaroid sunglasses. They minimise the glare caused by sunlight for drivers to see through windows and fishermen to see more clearly under the water surface. A few other applications of polarisation include:

Polarisation is a fundamental property of electromagnetic waves that is related to many applications in our daily lives.
