Yes, internal waves have been directly observed, particularly in oceans and large lakes. These waves occur within the water column, typically at the interface between layers of different densities. Researchers use various methods, such as acoustic Doppler current profilers and underwater cameras, to capture and study their behavior. Observations have confirmed their existence and provided insights into their impact on ocean mixing and marine ecosystems.

Before Heathcliff died, Ellen observed that he had become unusually calm and reflective, almost as if he was preparing for his end. This change in demeanor was striking, as he had previously been consumed by bitterness and revenge. Additionally, he seemed to be haunted by a sense of longing and nostalgia, particularly regarding Catherine, which added to the eerie atmosphere surrounding his final days. His transformation suggested a deep internal conflict and resignation to his fate.
They wouldn't have called them tsunamis because that's a Japanese word, but any tidal waves and their usual cause, earthquakes, would have been blamed on Poseidon.
When Holmes saw the return train ticket in Helen Stoner's hand, he could deduce that she came to London by train. When Holmes observed the fingermarks on Helen Stoner's arm, he was able to deduce that she must have been abused. When Holmes observed that the bed was clamped to the floor, he deduced that someone had a strong reason for keeping the bed in place. When Holmes observed the saucer of milk in Dr Roylott's room, he could deduce that there must be some type of creature inside the house.
Alderaan, however when he arrives in the Millennium Falcon he finds that it has just been destroyed by the Death Star
Yes, exoplanets have been observed directly through techniques such as imaging and spectroscopy. Direct imaging involves capturing light from the exoplanet itself, while spectroscopy helps determine the planet's composition by analyzing its atmosphere.
VSEPR is a conceptual model, as it has not been directly observed.
Sounds plausible. Unfortunately, gravity waves have been laboriously tested for and searched for, but have never been observed yet.
How was the planet Uranus been observed
No, Higgs Boson is a theoretical particle yet to be observed directly or indirectly by humans. Quarks on the other hand have been observed directly and indirectly. Also, the Higgs boson is responsible for a field, however quarks are responsible for matter, and are the basic constituents of the nuclei in atoms.
None have been directly observed. Our ability to analyse in detail the structures of the human anatomy is fairly new. In the short time since we've been able to map neural structures and neurochemical patterns, no significant evolution can be expected to have occurred.
Judgement based on what has been observed is a conclusion.
The Higgs boson. In fact, it has not been observed by 2011.
XeOF4 is prepared by reacting xenon hexafluoride with oxygen. On the other hand, XeO2F4 is not directly prepared from xenon as it is a hypothetical compound that has not been experimentally observed or synthesized.
Seismic waves such as P-waves and S-waves have been crucial for seismologists in studying the Earth's interior. These waves travel through the Earth at different speeds and can provide information about the composition, density, and structure of the Earth's layers. By analyzing how seismic waves behave as they pass through the Earth, seismologists can gain insights into its internal properties.
Gamma waves are high-frequency brain waves (above 30 Hz) associated with higher mental functions like problem-solving, learning, and memory. They are involved in coordinating signals from different brain areas and are often observed during cognitive tasks that require focus and attention. Gamma waves have been linked to enhanced perception and sensory information processing.
"Observed" is a word that means something has been noticed.
