Is a boat propeller a type of inclined plane?
No, a boat propeller is not a type of inclined plane. An inclined plane is a simple machine that consists of a sloping surface while a boat propeller is a rotating device that moves the boat through water by creating thrust.
What are the properties of surface waves?
The basic properties of transverse waves are: Amplitude Time Period Frequency Phase Wavelength Crest Trough
Which parameter of light doesnt change on reflection?
Frequency is the parameter of light which doesnt change on reflection because it is the ratio of velocity of light in medium and wavelength of the particle.Hence,when velocity increases wavelength also increases and when velocity decreases wavelength also decreases but its ratio always remains constant.
How does a propeller work?
A propeller works by converting the rotation of the engine into horizontal thrust similar to a fan. The blades push the air backwards creating acceleration, and create a difference in pressure between the forward and rear surface adding to the movement. The above is, of course true for a boat propeller. For an airplane propeller Bernoulli's pincipal is involved. Bernoulli's principle states that the greater the speed of a fluid, the less the lateral pressure. So the propeller uses the same deal as the wing.
Does wavelength of the incident rays play a role in the phenomenon of photoelectric effect?
Yes, the wavelength of the incident rays plays a role in the photoelectric effect. The phenomenon is influenced by the energy of the photons, which is inversely proportional to the wavelength of the incident light. Shorter wavelength light (higher energy photons) is more likely to cause the emission of electrons from a material in the photoelectric effect.
What happens to reflected waves?
Reflected waves bounce off a surface when they encounter it, changing their direction but not their frequency or wavelength. The angle of reflection is equal to the angle of incidence, according to the law of reflection.
What is threshold wavelength?
Threshold wavelength refers to the minimum wavelength of light required to start a specific phenomenon, such as photoelectric effect or emission of electrons from a metal surface. Below this threshold wavelength, the desired effect does not occur.
A ray wavelength 680nm propagates into a tank of liquid alcohol at an angle of 36.9 from the surface of the liquid calculate the speed and the wavelength of the refracted red light ray in alcohol?
The frequency of the laser in the alcohol will be 680nm and the speed of light as always, is 299,792,458 meters per second. Why did you need to ask this?
What is the shortest wavelenght radiation from the sun?
The shortest wavelength radiation from the sun is in the form of gamma rays, which have a very high frequency and energy. These rays are absorbed by the Earth's atmosphere and do not reach the surface.
How are transverse longitudinal and surface waves similar?
Transverse, longitudinal, and surface waves are all types of mechanical waves that transport energy through a medium. They all have characteristics such as amplitude, frequency, wavelength, and speed. These waves can be described by their propagation direction relative to the direction of the wave motion.
Why does decrease loudspeaker dimension with loudspeaker frequency?
At low frequency, a large diameter speaker moves with the entire surface area in phase. But at a specific frequency, dependent on the speed of sound in the membrane material and the diameter, the surface closest to the drive point and the outer edges of the surface starts to move out of phase. The speaker wobbles, creating distortion and decreased sonic output. So a large area speaker is by this reason less well suited for reproducing high frequency signals. Also, a large speaker is heavy, and is harder to accelerate. This also limits the high frequency reproduction. Adversely, a small area speaker needs to move far, have a high amplitude, to reproduce low frequency signals, creating Doppler distortion and unlinear reproduction. One way to solve these problems is to divide the signal between two or more drivers of different sizes.
Why does a prism refract white light to several different colors?
White light is actually a mixture of different colors, each with a different wavelength. When white light enters a prism, it is refracted at different angles based on its wavelength due to the phenomenon of dispersion. This causes the white light to separate into its constituent colors, creating a rainbow effect.
