The answer is 4, 6 and 7. Gas and plasma share most similar properties. The difference lies in the fact that plasma is composed of ions and electrons (ionized gas) as opposed to gas that is composed of neutral molecules. Therefore plasma can conduct electricity while gas cannot.

Lenses are described as convergent or divergent depending on how they refract light. What is the difference between these two ty

Umnica [9.8K]

Answer:

Explanation:

Convergent lens is the lens which converges the rays of light falling on it. It is thicker at the middle and thinner at the edges. It is also known as convex lens.

Divergent lens is the lens which diverge the rays of light falling on it. It is thinner at the middle and thicker at the edges. It is also called as concave lens.

What is the thinnest film (but not zero) that produces a strong reflection for green light with a wavelength of 500 nm ?

Marizza181 [45]

The thinnest film (but not zero) that produces a strong reflection for green light with a wavelength of 500 nm is 200 nm.

The wavelength of mild, λ = 500 nm

= 500 x 10^-9 m

Refractive index of oil, n1 = 1.25

Refractive index of water, n2 = 1.33

The thickness of the movie, d =?

For a sturdy mirrored image, m = 1

Wavelength, λ= 2 n1 d / m

Thickness, d = λ m / 2 n1

= 500 x 10 -9 * 1 / ( 2 * 1.25 )

= two hundred x 10 -nine m

= 2 hundred nm.

Wavelength is the gap between the same factors (adjacent crests) within the adjacent cycles of a waveform signal propagated in space or alongside a wire. In wireless systems, this duration is usually specified in meters (m), centimeters (cm), or millimeters (mm).

Wavelength may be defined as the space between two successive crests or troughs of a wave. it is measured within the route of the wave.

Wavelength is the distance among two adjacent crests or troughs of a waveform signal propagated in space or along a wire. The wavelength of a wave is usually specified in meters (m), centimeters (cm), or millimeters (mm). The wavelength is inversely related to frequency.

What is the least value of an ammeter Is it 1. 0.1 2. 0.10 3. 0.2 4. 0.5

givi [52]

The least value varies depends on ammeter range. In the given question, ammeter range is not mentioned. So, the least value of an ammeter is 0.1 or 0.5 (depends on ammeter range).

Explanation:

The least value of an ammeter is the measure of the smallest number which can be observed in ammeter. So the least value will be varying depending upon its range. If we consider the range of ammeter is 30 A and the scale readings are 10 numbers, then the least value will be 30/10 = 3 A per scale.

So the least value is determined as $\frac{Range of ammeter}{No.of scales}$
