Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling in various media.
One 2022 tsunami may have been as tall as the Statue of Liberty
A massive volcanic eruption in the South Pacific, earlier this year, appears to have triggered one tsunami that was initially 90 meters (nearly 300 feet) tall.By Sid Perkins

Let’s learn about music
Researchers are delving into how instruments and spaces shape our experience of music, and how computers could play a role in the future of music-making.
Coastal cities around the world are sinking, satellite data show
Of 99 coastal cities studied, nearly one-third are sinking. This leaves coastal communities increasingly vulnerable to rising seas.
Orb-weaving spiders use their webs like external eardrums
Scientists discover that orb-weaving spiders listen with their legs, detecting sound vibrations that travel through their silken webs.
A star called ‘Earendel’ could be the most distant ever seen

Muons reveal the inner worlds of pyramids, volcanoes and more
Tracking these subatomic particles can uncover surprising hidden structures.
Gravitational waves ‘kicked’ a newborn black hole across space
Two black holes merged into one, and then sped off at around 5 million kilometers (3.1 million miles) per hour.
We finally have an image of the black hole at the heart of our galaxy
New observations from the Event Horizon Telescope reveal the chaotic region around the Milky Way’s central black hole, Sagittarius A*, in extreme detail.By Liz Kruesi
Analyze This: Some 5,000 planets orbit stars other than our sun
A new cache of confirmed exoplanet discoveries marks a milestone in planets found beyond our solar system.
Night lights make even the seas bright
Light from coastal cities and offshore development may shine deep enough to disrupt tiny critters living dozens of meters (yards) below the surface.
Scientists Say: Doppler effect
The Doppler effect is a perceived change in the frequency of light or sound waves due to the wave source moving relative to an observer.
The Alps’ Matterhorn shows how much even big mountains sway
Such mountain sway data can help planners map high-risk zones for peaks, bridges or any large structures.By Peg Lopata
