ripples‚ but the waves transfers energy from one point to another. there are two major classes of waves ; mechanical and electromagnetic waves . Mechanical waves are waves that require a material medium for their propagation‚ such as water waves and sound waves. Electromagnetic waves are waves that do not require a material medium for their propagation. Examples are light rays‚ radio waves‚ x-rays and gamma rays. wave motion The particle of the medium which transfer energy move to and fro‚ or vibrate

Measuring the Speed of Sound and Air using a Pulse-Echo Technique Purpose To determine the speed of sound in air using the pulse-echo experiment procedure‚ and comparing it to the predicted speed of sound in air using the measured air temperature of the classroom. Hypothesis I believe that the speed of sound it the air will be close to that of the predicted value. According to our predicted value‚ we should expect the speed of sound in the air to be at a speed of approximately 346 m/s. Materials

In this stage babies put their trust into their parents to keep them safe from things that can harm them. In this stage you learn that the temperature of something can cause harm‚ that what we put in our mouth can taste gross‚ and that sometimes if we look at things we might have to look away.
