Which photon has the highest wavelegnth 10.2 or 2.1eV?
The photon with the higher energy (more eV in this case) has the higher frequency, and thus the lower wavelength.
What is the speed of radio waves with a wavelegnth of 4.2m?
The speed of any electromagnetic waves (and that includes radio waves) in a vacuum is always the same - approximately 300,000 km/second. The wavelength is irrelevant.
Do radio waves have the shortest wavelegnth of all EM waves?
No. In fact, when people try to carve up the EM spectrum into categories and typesand classifications and then name each part, they usually wind up giving the name"radio waves" to the part with the longestwavelengths.
Is the wavelegnth of a wave define as the distance between 2 consecutive identical points?
No, the wavelength of a wave is defined as the distance between any two points which are in phase with each other. Two points in phase only when they are moving with the same velocity in the same direction and are at the same displacement from the mean position.
What is the wavelegnth with afrequency of 10 hertz?
30,000,000 meters electromagnetic (radio). Depending on the altitude and temp. A 10Hz sound wave at sea level would be about 34.4 meters long.
What color has the longest wavelegnth?
The color with the longest wavelength in the visible spectrum is red, which ranges from about 620 to 750 nanometers. Wavelengths longer than red fall into the infrared spectrum, which is not visible to the human eye. As the wavelength increases, the color shifts through the spectrum, with red representing the longest visible wavelength.
What is the relationship among wavelegnth and wave velocity?
The relationship between wavelength and wave velocity is inversely proportional. This means that as the wavelength of a wave increases, the wave velocity decreases, and vice versa. This relationship holds true for all types of waves, including electromagnetic waves and mechanical waves.
In a wave of light why are frequency and wavelegnth important?
Frequency and wavelength in a light wave are important because they determine the energy and properties of the light. The frequency determines the color of the light, with higher frequencies corresponding to bluer colors and lower frequencies to redder colors. The wavelength affects how the light interacts with different materials and influences properties like diffraction and interference.
What is galaxy redshifted?
Galaxy redshift is much light the Doppler effect. If a galaxy is traveling away from us, the light that it emits and is seen by us is stretched out (the faster we are separating, the stronger the redshift), that means that the wavelegnth is stretched a bit, shifting the light towards red.
What is the wavelength of electromagnetic radiation if its frequency is 3.2 times 10 -2Hz?
The wavelength of electromagnetic radiation can be calculated using the formula: wavelength = speed of light / frequency. Plugging in the values (speed of light = 3.00 x 10^8 m/s, frequency = 3.2 x 10^2 Hz), the wavelength would be approximately 9.38 x 10^6 meters.
How are wavelength and frequency related to each other?
Wavelength is the distance a wave travels during a single, complete cycle. It can be measured by the distance between two crests of the same wave, and is reported in meters. Frequency pertains to how many of these cycles a wave completes in one second. The unit of frequency is the Hertz (Hz), or cycles per second.The wavelegnth and frequency of any wave are inversely related to each other. That is, if the wavelegnth gets bigger, the frequency gets smaller, and vice versa.For electromagnetic radiation, including light, wavelength and frequency are related to each other by the speed of light: c=wavelength*frequency where c=3.00 x 10^8 m/s2 (approximately).It should be noted that this is the speed of light in vacuum, so if your wave is propagating through a medium such as water or a particular solid, this must be taken into account.Questions you will usually encounter in intro physics classes will involve waves traveling through air or vacuum, in which the approximate velocity given above holds for both. Also, if you are given an angular frequency (commonly denoted by a lowercase omega) in radians, you must convert it to Hz as follows: frequency=omega/(2*pi) in order for the above relationship to hold.
What is the equation for radiation pattern of a half wave dipole antenna?
E=sin(Theta); You need to normalize the equation for the electric field of the half-wavelegnth dipole. recall E=sqrt(ExE*) where E* is the conjugate of the E field. This is why you only get an eight shaped figure (or infinity symbol) when you plot it. you will get this figure if the dipole is placed in the axis of interest. e.g. if it is in the placed in the x axis, you will get an eighth in the x-y,x-z, but you will get a donut shape in the y-z (no angle to measure) hope this helps a bit.
