For the reflection of sound waves, a hard, smooth surface such as a wall, floor, or metal sheet is required. These surfaces reflect sound effectively, causing minimal absorption and scattering of the waves.

The reflection of sound waves is governed by two main laws: the angle of incidence equals the angle of reflection, and the incident sound wave, reflected sound wave, and the normal (perpendicular) to the surface at the point of incidence all lie in the same plane.

A real-life example of a transverse wave is a light wave. In light waves, the oscillations of the electric and magnetic fields are perpendicular to the direction of wave propagation.

Fertilizers should be applied carefully to avoid over-fertilization, which can harm plants, contaminate water sources, and disrupt ecosystems by causing nutrient imbalances and promoting excessive algae growth in water bodies.

If fertilizers are not fully absorbed by plants, they can leach into groundwater, runoff into rivers and lakes, causing water pollution, algal blooms, and eutrophication, which deplete oxygen and harm aquatic life.

Certain moths use their sensitivity to ultrasonic sound to detect and evade echolocating bats. By hearing the ultrasonic calls, moths can perform evasive maneuvers or even produce their own ultrasonic clicks to confuse predators.

Frequencies higher than 20 kHz are called ultrasonic sounds. Animals that produce these sounds include bats for echolocation, dolphins for communication and navigation, and some insects like moths for predator detection and evasion.

Some animals might detect earthquakes before humans due to their heightened sensitivity to seismic waves and changes in the environment, such as shifts in electromagnetic fields, enabling them to sense tremors and vibrations that precede an earthquake.

Elephants use infrasound for communication, with frequencies as low as 14-35 Hz. Blue whales also communicate using infrasound, producing calls between 10-40 Hz that can travel across vast ocean distances.

The minimum distance required for hearing distinct echoes is calculated using the formula: distance = speed of sound × (time for echo to return) / 2, ensuring the echo delay is at least 0.1 seconds for perception.
