The greater the mass of a substance of a given temperature, the more thermal energy it has. or substance is temperature. When temperature is higher, the object or substance has more thermal energy.
Answer:
Melting point is the temperature at which a a solid melts
Explanation:
Answer:
microsecond = 1 × 10-6 seconds
1 second = 1 × 100 seconds
1 microsecond = (1 / 1) × 10-6 × 10-0 seconds
1 microsecond = (1) × 10-6-0 seconds
1 microsecond = (1) × 10-6 seconds
1 microsecond = 1 × 1.0E-6 seconds
1 microsecond = 1.0E-6 seconds,just do like it
(a)
The relationship between frequency and wavelength of an electromagnetic wave is given by
where
is the speed of light
is the frequency
is the wavelength
In this problem, we are considering light with wavelength of
Substituting into the equation and re-arranging it, we can find the corresponding frequency:
(b)
The period of a wave is equal to the reciprocal of the frequency:
And using as we found in the previous part, we can find the period of this wave:
The refractive index of a medium is independent of (not related to) the angles of incidence or refraction. It's just a property of the medium. <em>(D)</em>
