the wavelength of any reflected or emitted photon or other particle is shortened in the direction of travel.
The wavelength of yellow sodium light in water is approximately 589 nanometers. This specific wavelength is characteristic of the spectral emission line of sodium when it is viewed through water.
Viruses. They are smaller than the average wavelength of light and as such are not viewable unless an electron microscope is used.
I assume you are asking in regard to the photoelectric effect. The intensity of the photons can be viewed as the brightness of the light. However, the frequency is the number of wavelengths that pass a certain point in a second. The frequency is also used to determine the energy of the photon (E=hf).
Ultrasound technology uses high-frequency sound waves to create images by sending these waves into the body. The waves bounce off internal structures and are then detected by a transducer, which converts them into an image that can be viewed on a screen. This allows healthcare professionals to visualize organs, tissues, and blood flow without the need for invasive procedures.
The appearance of a flat horizon when viewed from a distance is caused by the curvature of the Earth.

At an apparent magnitude of 3.4, the Andromeda Galaxy is one of the brightest Messier objects, making it visible to the naked eye on moonless nights even when viewed from areas with moderate light pollution.

The Andromeda Galaxy is spiral shaped, much like our own Milky Way Galaxy.See related link for a pictorial.
Viruses. They are smaller than the average wavelength of light and as such are not viewable unless an electron microscope is used.
Andromeda is visible best during the fall and winter months, particularly from late August to early March in the northern hemisphere. It is most easily seen during these times when it is high in the sky and away from any light pollution.
