The wavelength of a wave is the length of one wave cycle. It can be measured in units of length, such as meters. The distance a wave travels in one period is one wavelength, so we can apply the constant speed motion equation to a wave like this: ...
(ii) Explain how the coherence condition for interference is obtained when a plane wave front meets a pair of narrow slits which are parallel to the wave front.[1](f) Light of wavelength 5.24 × 107 m is shone on a double slit whose separation is0.220 mm. Calculate the separation of th...
What is scanning electron microscope? What is a scanning electron microscope used for? How to find the wavelength of a photon How to measure refractive index of thin films How to calculate frequency of a photon How to determine the wavelength of the incident photon?
is about 5 m s-1.(3) d d (e)The velocity of longitudinal waves in the spring is also determine d by finding the time for a pulse to travel along the length of the spring.The spring is filme d while a pulse is create d at the bottom an d allowe d to reflect from the top....
and different techniques should be used for prediction of these properties. However, some characteristics of all waves are common and can be used to distinguish between various wave types. The most important characteristics are relative wavelength (L/h), relative wave height(H/h)and wave steepness...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
determine the telescope's field of view: apparent - how much of the sky, in degrees, is seen edge-to-edge through the eyepiece alone (specified on the eyepiece; true or real - how much of the sky can be seen when that eyepiece is placed in the telescope (true field = apparent field...
Waves can describe sound, light or even the wavefunction of particles, but every wave has a wavenumber. This describes how it varies through space, and this depends crucially on the wavelength of the wave or its speed and frequency. For physics or chemistry students, learning to calculate a ...
Wavelength is the distance between any point on a wave and the corresponding point on the next wave. Technically, sound is defined as a mechanical disturbance traveling through an elastic medium — a material that tends to return to its original condition after being deformed. The medium doesn'...
To cover all relevant length scales one usually needs to combine several methods. Optical methods are limited by the wavelength of the light and the shortest length scales that can be probed are usually of order\(\sim 1 \ \mathrm{\mu m}\). The (maximum) resolution of stylus measurements ...
