Answer:
Explanation: Isotopes generally have same proton number and electron number. Their mass number and neutron number is different.
Neutron number =mass number -proton number
Answer:
Explanation:
Using Snell's law which is represented by
Making the subject of the formula then
Here and are the angles of incidence and refraction in water and air respectively
and are refraction index
Substituting 1.0003 for and 1.33 for then for we obtain
Answer:
Constructive interference: destructive interference
Explanation:
Constructive interference occurs when waves are in phase or sync with one another and will lead to brighter and bolder results while destructive interference occurs when waves are out of phase with one another.
In this scenario, light passing through two slits creates a pattern of bright and dark fringes on a screen. The bright fringes result from constructive interference ; the dark fringes result from destructive interference.
Radiation is the only one that can pass through a vaccum (like space). You need a medium for conduction and convection to work. Therefore the answer is radiation.
