Explanation

• Sound travels fastest in diamond, with a speed of approximately 12,000 meters per second (m/s).
• This is because diamond has a very high stiffness and density, which allows sound waves to propagate quickly through the material.

The speeds of sound in different materials:

• Air: 343 m/s
• Water: 1433 m/s
• Wood: 3300-3600 m/s
• Brick: 4176 m/s
• Steel: 6100 m/s
• Diamond: 12000 m/s

All important questions and Information Related to 'Photosynthesis"

Photosynthesis takes place in presence of the following light Only in sunlight from the sun

Photosynthesis takes place faster in white light

Photosynthesis occurs more in blue and red light rays

Photosynthesis occurs more in blue and red light rays and less, or not at all, in green light rays.

Green Light light is more important for photosynthesis.

As compared to photosynthesis, glucose is chiefly decomposed during Respiration

At the time of a Solar Eclipse, the rate of photosynthesis will: Decrease

In all plants, the major sites of photosynthesis are Leaves

In Photosynthesis reduction occurs in the Water

At night, when photosynthesis is stopped, plants Give off Carbon Dioxide.

Photosynthesis pigments are organized into clusters called thylakoid

The process of photosynthesis produces glucose and carbon dioxide

Explanation

• The lungs are the organs responsible for exchanging oxygen and carbon dioxide through the process of respiration.
• They consist of air-carrying tubes (bronchi and bronchioles) and tiny sacs (alveoli) where gas exchange occurs.

Explanation

A chronometer meter measures time .

Chronometer is to measure accurately the time of a known fixed location

for example Greenwich Mean Time (GMT).

Explanation

Explanation

• A barcode reader, also called a price scanner or point-of-sale (POS) scanner.
• It is a hand-held or stationary input device.
• It used to capture and read information contained in a barcode.

Explanation

Explanation

• Wavelength is the distance between two consecutive points on a wave that are in phase with each other.
• Such as two crests or two troughs.

Explanation

Decibel (dB) is the unit used to measure sound intensity.

Which is related to the amplitude of a sound wave.

The amplitude of a sound wave determines the loudness of the sound

One decibel (0.1 bel) equals 10 times the common logarithm of the power ratio.
