MS-PS4-1
Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.
- Physics
Scientists Say: Gamma ray
Lightning bolts, nuclear explosions, colliding stars and black holes all throw off this high-energy type of light.

Talking through a tube can trick AI into mistaking one voice for another
Researchers crafted tubes that can trick AI into mistaking one person’s voice for another’s. Bad guys could use such tricks to hack into accounts.
- Physics
Scientists Say: Ultrasonic
This word describes sound waves that have frequencies too high for human ears to hear.
- Physics
Scientists Say: Radio Waves
Lightning, stars, supermassive black holes and more give off radio waves.

Explainer: Reflection, refraction and the power of lenses
The inner workings of microscopes, telescopes, eyeglasses and other lens-based devices rely on two important laws of optics.

Think of this new tech as sunglasses for our windows
Keeping buildings cool can use a lot of energy. Thanks to quantum computing, engineers designed a coating to cut the warming light that enters windows.
- Earth
Scientists Say: Seismology
Seismology is the branch of science focused on seismic waves — vibrations that run through or around Earth.

Cosmic timeline: What’s happened since the Big Bang
Energy, mass and the cosmos' structure evolved a lot over the past 13.82 billion years — much of it within just the first second.

Explainer: How the Doppler effect shapes waves in motion
The Doppler effect describes how waves are compressed or stretched when their source — or receiver — is moving.
- Archaeology
Muons reveal the inner worlds of pyramids, volcanoes and more
Tracking these subatomic particles can uncover surprising hidden structures.

Wild art? No, it’s a radio image of the heart of our Milky Way
Eyelash-like radio filaments accent the brightest feature in this image — a supermassive black hole.

Explainer: How loud is too loud?
Loud sounds, be it music or noise, might seem like no big deal at the time. But permanent damage can occur without noticeable warning signs.
