What is the traditional construction material used for building houseboats in Kerala?
-
Wood
-
Metal
-
Fiberglass
-
Concrete
A
Correct answer
Explanation
Houseboats in Kerala are traditionally constructed using locally sourced wood, primarily jackwood and bamboo. These materials are known for their durability and resistance to the humid and tropical climate of the region.
What is the primary material used in the fabrication of optical fibers?
-
Glass
-
Plastic
-
Metal
-
Ceramic
A
Correct answer
Explanation
The primary material used in the fabrication of optical fibers is glass. Glass is a transparent material that is made by melting sand and other materials together. It is a good choice for optical fibers because it is strong, durable, and has a low refractive index.
What is the primary material used in the fabrication of laser diodes?
-
Gallium arsenide (GaAs)
-
Indium gallium arsenide (InGaAs)
-
Aluminum gallium arsenide (AlGaAs)
-
All of the above
D
Correct answer
Explanation
The primary materials used in the fabrication of laser diodes are gallium arsenide (GaAs), indium gallium arsenide (InGaAs), and aluminum gallium arsenide (AlGaAs). These materials are all semiconductors that have a direct bandgap. A direct bandgap means that the energy levels of the valence band and the conduction band are aligned. This allows electrons to easily move from the valence band to the conduction band, which results in the emission of light.
What is the primary material used in the fabrication of photodiodes?
-
Silicon
-
Germanium
-
Gallium arsenide
-
Indium gallium arsenide
A
Correct answer
Explanation
The primary material used in the fabrication of photodiodes is silicon. Silicon is a semiconductor material that has a direct bandgap. A direct bandgap means that the energy levels of the valence band and the conduction band are aligned. This allows electrons to easily move from the valence band to the conduction band, which results in the generation of an electric current when light is incident on the material.
Which material is often used in the production of hockey sticks due to its strength and durability?
-
Wood
-
Composite Materials
-
Metal
-
Carbon Fiber
B
Correct answer
Explanation
Composite materials, such as fiberglass and carbon fiber, are commonly used in the production of hockey sticks due to their strength, durability, and ability to withstand the impact of the puck.
What was the primary material used in early 3D printing processes?
-
