Answer:
We can use optical fibers.
Explanation:
The optical fibers are the optical devices which is based on the total internal reflection.
The optical fiber has two layers, one is called core and the other is called cladding.
The refractive index of core is more than the cladding.
As a ray of light falls on the core at more than the critical angle for that pair of media(core and cladding), it suffers the total internal reflection at the interface.
Answer
given,
B = 6.40 mm , L = 26 cm , τ = 3.90 × 10⁻² s
general wave equation
y = A cos (k x - ωt)
where A is the amplitude of the
a) Amplitude of the given wave
B = 6.40 mm
b) Wavelength of the given wave
λ = L
λ = 26 cm
c) wave frequency
f = 25.64 Hz
d) speed of wave will be equal to
v = f λ
v = 25.64 x 0.26
v = 6.67 m/s
e) direction of propagation will be along +ve x direction because sign of k x and ωt is same as general equation.
Answer:
Temperature difference in kelvin =7K
Temperature difference in Fahrenheit degree = 12.6°F
Explanation:
Temperature difference = 7°C
273 is added to the Celsius value to convert to kelvin temperature.However if 273 is added to both the initial and final values of the Celsius temperature values, then the difference still stays the same. Hence the difference in kelvin is 7K.
To convert the temperature difference to Fahrenheit we simply multiply 1.8
=7*1.8 = 12.6°F
Answer:
Cold blooded animals are those animals that cannot regulate their body temperature and their temperature keeps changing according to their environment. ... Warm blooded animals are the animals that have a constant body temperature and can easily adapt to extreme temperatures as they can regulate their body temperature.
