Our planet vibrates incessantly, sometimes with notable but more often with imperceptible intensity. Conventional seismology attempts to decipher vibrational sources and path effects by studying seismograms—records of vibrations measured with seismometers. Anthropogenic (human) activities at Earth's surface also generate seismic waves that instruments can detect over great distances. On page 1338 of this issue, Lecocq et al.

Capturing songs and calls can open a whole new level of birding—but equipment can be daunting. Here’s what you need to know to get started. Setting out to record birdsong for the first time can be a surprisingly risky endeavor. “There’s a danger whenever anybody picks up recorders and headphones,” warns Donald Kroodsma, who has written several books about birdsong and spent hundreds of hours in the field with a microphone. “You can get hooked for life.” Great Backyard Bird Count, Backyard Birds, Hummingbird Garden, Hummingbird Nectar, Bird Guides, Common Birds, Audubon Birds, Audubon Society, Birds Of America

Sound is a form of energy that is caused by the vibration of matter. Sound is transmitted through waves, which travel through solids, liquids and gases. We are most used to the sound travelling through air, but sound is able to travel faster and further in solids and liquids.

A standing wave is the combination of two waves that are moving in opposite directions. Standing waves are typically formed in situations where a wave is bouncing back and forth in an environment that produces constructive interference. To put this more simply, a standing wave occurs when the length of the wave matches the length of the environment. To understand why standing waves behave the way they do, consider what happens when you send a single pulse (0.5 of a wave) down a rope that...

In this activity, students play different kinds of sounds near a computer’s microphone and watch the resulting visual display created by oscilloscope software. By the end of this activity, students should be able to: relate the visual display to each sound played; and appreciate the complexity of amplitudes and frequencies within real sounds.

Fundamentals of waves - TEACHING RESOURCE. Seeing, hearing, feeling warmth, surfing, tuning the radio, using a cellphone – these and many more activities involve waves. But what is a wave? In this article, we get to grips with the different kinds of waves and look at the key characteristics of all waves – their wavelength, period, frequency, speed and amplitude. These concepts are important for describing waves of all kinds. Physical Science, Science Projects, Science Experiments, Science Education, Science Activities, School Projects

Sound in water - VIDEO. Prof John Montgomery, the head of Auckland University Leigh Marine Laboratory, explains how sound travels in water and how this is different to how sound travels in air. He explains why sound can travel so much further in the ocean compared to on land. Point of interest: In this clip. you’ll hear the ‘song’ of the humpback whale. The humpback whale song is known to travel large distances through the ocean. Whale Song, Humpback Whale, Explain Why, Montgomery, University, Ocean
