Qps = No. of persons x Kcal / h (sensible) table per person depending on activity.
Visual Perception and Image Analysis in Mass Media
1. Visual Perception and Image Analysis
1.1 The Impact of Television
The emergence of television in the 1940s transformed mass media and the way people think. Advertising utilizes television’s visual power to capture attention and create needs.
The image, as defined by Moles, is a visual communication tool that materializes a fragment of the surrounding environment and forms a crucial component of mass media. Initially perceived as a means to reproduce reality, photography’s artistic potential and

Compression and Rarefaction
Sound waves create areas of varying pressure as they travel. High-pressure zones with tightly packed molecules are called compressions, while low-pressure zones with loosely packed molecules are called rarefactions.
Beats
Beats are fluctuations in loudness caused by the interference of sound waves with slightly different frequencies. The beat frequency is the difference between the frequencies of the two interfering waves.
Categories of Sound Waves

Understanding Light Qualities in Photography and Film
Item 42: Understanding Light Qualities
1. Qualities of Light
Light travels in straight lines called rays. When light hits an object, it can be:
- Reflected: Bounces off the surface.
- Refracted: Bends as it passes through the object.
- Scattered: Passes through and breaks into multiple rays.
- Diffracted: Bends around the edge of an object.
2. Quality of Light
Light quality depends on the directionality of light rays. There are three main types:
- Hard Light: Strong direction, creates sharp shadows (e.g., sunlight)
The English Consonant System
The consonant system of Received Pronunciation (RP) consists of twenty-four consonants.
Phonetically, a consonant is a speech sound in which the airstream from the lungs is obstructed or the mouth passage is so narrow that the air is expelled with audible friction. The sounds /j/ and /w/, which we term semivowels, are classed as consonants on functional grounds, but they have exactly the same articulatory characteristics as vowels.
Classification of Consonants
Consonants are generally classified according

Neoplasticism: A New Artistic Movement
Neoplasticism, a Dutch artistic movement, emerged as a response to the destructive irrationality of World War I. It sought to establish a new form of geometric abstraction based on reason and ethics. Key characteristics of Neoplasticism include:
- Simplicity: Eliminating unnecessary
