Answer:
65m
Explanation:
Twelve waves pass a dock in 3.60 If the waves are traveling at 19.5 m/s , what is the wavelength of the waves?
Velocity of a wave is expressed as;
V = frequency × wavelength
Given
Velocity = 19.5m/s
Frequency is the number of oscillations completed in 1sec, hence
Frequency= 3.6/12
Frequency = 0.3
Wavelength = vel/freq
Wavelength = 19.5/0.3
Wavelength = 65m
electric potential energy..electrons get the the kinetic energy from the voltage applied across the conductor
Answer: 117.8 nm
Explanation:
Given,
Nonreflective coating refractive index : n = 1.21
Index of refraction: 
= 1.52
Wave length of light = λ = 570 nm = 
Hence, the minimum thickness of the coating that will accomplish= 117.8 nm
Answer:
The SI unit of intensity is the watt per square meter/metre (W/m^2.)
Explanation:
Intensity is equal to the power transferred per unit area. Since power is measured in watts (W) and 1 W = 1 J/s, then intensity can be viewed as how fast energy goes through a certain area.
In physics, intensity is often used when studying light, sound, or other phenomena that involve waves or energy transfer. (With waves, the power value is taken as the average power transfer over the wave's period.)
