Answer:

No Refraction takes places

Explanation:

When light travels from one medium to another at an angle of incidence 0 degree then no refraction takes place .

It is because according to Refraction law

                    n_{i}sini = n_{r}sinr

where n_{i} ,n_{r} are the refractive index of medium of incidence and medium of refraction .

When i = 0 , left side of the equation becomes 0 and thus r (angle of refraction) must be zero. So No refraction takes place

How much time does it take light to travel from the moon to the earth, a distance of 384000 km?
Natali5045456 [20]

Answer:

1.28second

Explanation:

The speed of light is constant everywhere, it is

299,792,458m/s=299,792.458km/s

Therefore it takes

\frac{384000}{299792458}  = 1.28sec

Which of the following are possible causes of mass extinctions that scientists have identified
Alecsey [184]

Answer:

over harvesting, pollution, introduction of invasive species such as new predators and food competitors

Explanation:

The main cause of mass extinction is Humans cause extinction of a species through overharvesting. The second main  cause is pollution ., introduction of invasive species such as new predators and food competitors, habitat destruction, overhunting and other influences. Another very important cause of mass extinction is the unsustainable human population growth.

The five mass extinction events are

Ordovician Mass Extinction

Devonian Mass Extinction

 Permian Mass Extinction

Triassic -Jurassic Mass Extinction

and Cretaceous -Tertiary (or the K-T) Mass Extinction.

The velocity of a wave is a function of its:<br><br> energy<br> form<br> medium<br> amplitude
algol [13]

Answer:

Amplitude.

Explanation:

The velocity of a wave is given by :

velocity = total distance covered/total time taken

In the case of a wave the total distance covered is equal to the amplitude of a wave. It is the maximum displacement covered by the wave. So, the velocity of a wave is a function of its amplitude. Hence, the correct option is (D).
