Explanation

• When light passes through a prism, refraction occurs, leading to the formation of a spectrum.
• Refraction is the bending of light as it passes through a medium with a different optical density.
• It causes the different wavelengths of light to separate and form a spectrum.

Explanation

Explanation

A supercomputer is another name for a high-performance computer (HPC).

Supercomputers are powerful computers that are designed to execute a large number of instructions at an extremely high speed.

It making them ideal for scientific simulations, weather forecasting, cryptography, and other compute-intensive tasks.

Explanation

• The molecular model of DNA that suggests the basic mechanism of replication was proposed by James Watson and Francis Crick.
• They proposed the double helix model of DNA in 1953, which revolutionized our understanding of genetic information storage and replication.

Explanation

• An optical instrument used to measure the properties of visible light is called a Spectroscope.
• It analyzes the composition and properties of materials based on the light they emit or absorb.
• It helping us understand the physical and chemical properties of objects in the universe.

Explanation

• Communication satellites are used for telecommunication.
• Including telephone communication, internet connectivity, and television broadcasting, enabling global communication networks.

Explanation

• Secondary consumers are organisms that eat primary consumers for energy. 
• In the above options, only goat is a primary consumer.
