The answer is The coastline experiences tidal bulge twice a day. This occurs due to the rotation of the earth. When the sun is either on the same side as the moon or opposite side of the moon relative to the earth (which happens twice a day), then the coastline will experience high tide on these two occasions. Tides are caused by gravitational effect on water masses on the earth that cause them to bulge towards the direction of the two celestial bodies.

From the transitions of ice to water, water to steam, steam to water,
or water to ice, mass doesn't change.
Answer:
1.08
Explanation:
This is the case of interference in thin films in which interference bands are formed due to constructive interference of two reflected light waves , one from upper layer and the other from lower layer . If t be the thickness and μ be the refractive index then
path difference created will be 2μ t.
For light coming from rarer to denser medium , a phase change of π occurs additionally after reflection from denser medium, here, two times, once from upper layer and then from the lower layer , so for constructive interference
path diff = nλ , for minimum t , n =1
path diff = λ
2μ t. = λ
μ = λ / 2t
= 626 / 2 x 290
= 1.08
