The wavelength of sound wave is 30 m. Frequency is 7 Hz. What is the wave speed
Answers
Thewave speed will be 210 m/sec. The wave speed is found as the product of the wavelength and frequency of the wave.
What is wavelength?
The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.
The relationship between the wave's wavelength, time, and speed is given as;
Wavelength = speed of wave / time period
Hence, the wave speed will be 210 m/sec.

The gaseous state of a liquid is called as vapor under normal conditions of temperature and pressure.
Answer: Option A
Explanation:
Vapor is a form of substance floating in air where increasing or decreasing the temperature and pressure changes the state of the substance into gas or liquid.
For example : consider water where heating it to the boiling point makes it as water vapor and reducing its temperature makes it as ice.
Under normal conditions of temperature and pressure, the gaseous state of a liquid is called vapor. The correct answer is A.
When a liquid is heated or its pressure is reduced, the kinetic energy of its molecules increases, causing them to gain enough energy to overcome intermolecular forces and transition into the gaseous state. This gaseous form of a substance, while retaining the same chemical composition as the liquid, is called vapor.
Let's examine why the other options are not true:
B. Water: Water specifically refers to the liquid state of H2O molecules. While water can exist as a liquid, solid (ice), or gas (water vapor), under normal conditions, the gaseous state of a liquid is referred to as vapor rather than water.
C. Smoke: Smoke is not the gaseous state of a liquid. It typically consists of tiny solid particles or liquid droplets suspended in the air, resulting from the incomplete combustion of organic matter. Smoke is not directly related to the gaseous state of a liquid substance.
D. Ice: Ice refers to the solid state of water. It is the result of the cooling and freezing of liquid water molecules. Ice is not related to the gaseous state of a liquid substance.
Therefore, under normal conditions of temperature and pressure, the gaseous state of a liquid is called vapor. While water refers to the liquid state, smoke is not directly related, and ice represents the solid state of a liquid substance.
