Lo5 - The Doppler Effect and Bats
The document discusses the Doppler effect, which is the change in frequency of waves due to relative motion between the source and receiver. It provides the Doppler equation and explains how the signs change depending on if the source and receiver are moving towards or away from each other. It then gives an example problem involving a bat using echolocation to detect prey. The bat emits a whistle and detects the echo off the prey. The problem is worked through step-by-step to calculate the frequency changes based on whether the bat and prey are moving towards or away from each other.

The Doppler Effect
The Doppler effect describes how the frequency of a wave (such as sound) is perceived by an observer who is moving relative to the source of the wave. When an ambulance approaches with its siren on, the observer hears a higher pitch tone due to compression of the sound waves. As the ambulance passes and moves away, the observer hears a lower pitch tone due to expansion of the sound waves. The Doppler effect can be calculated using an equation that takes into account the velocity of sound, velocity of the source, and velocity of the receiver.

Bariatrija ir medicīnas nozare, kas aptaukošanos slimību ārstē ar ķirurģiskām metodēm.
Ar bariatrijas ķirurģiju ir iespējams - atbrīvoties no liekā svara un panākt II tipa cukura diabēta remisiju. Pateicoties šādai terapijas metodei būs iespējams ieekonomēt milzīgos valsts budžeta izdevumus, kas tiek iztērēti CD un tā komplikāciju ārstēšanai.

Signe Mežinska: Racionāla zāļu lietošana
Medikamenti ir ne tikai ķīmiskas vielas, kas fiziski ietekmē cilvēka organismu, bet arī sociāls un kultūras fenomens, kura nozīmi lielā mērā veido priekšstati, idejas un emocijas.

Doppler Effect
The document discusses the Doppler effect, which is the change in observed frequency of a wave caused by movement of the source relative to the observer. Specifically, the frequency increases as the source approaches and decreases as it moves away. This effect was first described by Christian Doppler in the 1800s. Real-world applications of the Doppler effect include police using radar to detect speeding vehicles and meteorologists tracking storm movements.

Doppler Effect
The Doppler effect describes how the frequency of a wave is altered by the motion of the source or receiver. There are three cases: a stationary source with a moving receiver, a stationary receiver with a moving source, and both moving. If the source and receiver move towards each other, frequency increases, and if they move apart frequency decreases. This is demonstrated by the Doppler effect equation. For example, an emergency vehicle's siren appears higher in pitch as it approaches a stationary listener due to the source moving towards the receiver.
Doppler effect
The Doppler Effect describes how the frequency of waves is altered by the motion of the source or observer. It was first explained in 1842 by Christian Doppler. When the source and observer are moving towards each other, the perceived frequency is higher than the actual frequency. When they are moving away from each other, the perceived frequency is lower. This shift in frequency due to motion is known as the Doppler Effect and applies to sound waves, light waves, and other wave phenomena.
DOPPLER EFFECT
The Doppler effect is the apparent change in frequency of a wave due to relative motion between the source and observer. It has applications including determining the velocity of moving objects, discovering Saturn's rings and the spin of the sun, and detecting binary stars and whether stars are moving toward or away from Earth. An example calculation shows an increase in observed sound frequency when a source emitting 1600Hz sound waves approaches an observer at 80m/s.
